25 More Ideas.

Alienation: "Have you ever been alone in a crowded room?"
Figures disappearing into the background due to light choices and the presence or absence of a pattern. Photography with editing to overlay interesting wallpapers to represent the idea of becoming part of the room and a wallflower. Anxiety in the poses of the figures.

Moral Ambiguity
Grey grey grey. Graphite drawings of figures in various situations in which the viewer must decide if it was right or wrong. For example the aftermath of a person shooting a gun, correct? Even if in self defense? How will that character view it? Perhaps these drawings shouldn't be crisp and clear but smudged with altered edges to show that there isn't a crisp clear answer or situation.

Appropriation: Is anything pure? Or connected from bits and pieces of everything else?
Create an image of an object made out of images that have nothing to do with it, or are directly related to it. Collage or digital collage. Working with value and color to create visual harmony.

Authenticity: What is "True"? Or Genuine? Memory isn't always authentic but constructed.
Digital collages of a scene, where the smaller images composing it are or are not directly related to it to show we have so many things in our memory it is difficult to remember what was relevant to that situation and forgotten. Images would blend together and obscure areas of the scene that are most irrelevant to show how focus is related with memory.

Body Image: How others see me, compared to how I see myself. Which matters?
Cindy Shermann inspired portraits that are paired together for how I view myself and how others view me. One could be they see me as too small compared to how I see myself as normal. The viewer wouldn't know which is which. Simple backgrounds that are related in each pair. Digital manipulation would be necessary to exaggerate points.

Censorship: Biting your tongue, forced to keep a secret, keeping your opinions to yourself to keep the peace.
Light generals wash drawings of figures trying to communicate but failing. A hand writing on white paper with a white pencil, a person screaming into the wind, books torn apart, wet text and images. Could be on top of ruined text that's hidden and distorted relating to issues of which people do not feel comfortable talking about in society.

Code: Unspoken moral codes, a secret language in order to say what you wish you could say.
Continuing the idea of numbers as code for letters from 1-9. Can be shown in literal. On texts such as bar odds, serial numbers, telephones, etc.. Or could be placed on top of a hot button or dramatic scenario in which I wish I could say something intense that myself could not say in a bold manner. Like Barbra Kruger with numbers, so that there is intent for a bold message but it is still censored via a code.

Cyborg: Attached to technology, it allows for more communication yet it is less personal. Losing actual human contact. Machine aesthetics for appearance via photoshop or surgery.
Anatomy style photographs superimposed with technology bits and pieces. How our hands are basically cell phones now, how we speak in limited language, our brains are becoming external hard drives. Shows how we our losing our humanity through so much dependence on technology, how it is limiting in our interactions socially.

Environment: Nature vs. nurture, which influence is most important? To feel stuck in your environment.
Show one central figure in four different states because they have been placed in four different environments. This shows how the environment can impact the psyche of one person, but it could be different depending on the figure. Prisms colored marker and colored pencil for intense color and shadow to relate to emotion.

Gender-bending: Stereotypes and expectations
Close cropped photographs of bodies dressed in the opposite sex's clothing and how one can be fooled by it because of our expectations placed on external costumes to depict sexuality. Black and white photographs to add to the confusion.

Heros: What is it like to watch your heros fall?
Pairs of a child happy with their hero doing something positive for them (a father placing a bandaid on their child) paired with an image of the father doing something negative (a father drinking too much.) The ideal image would include colored pencil while the negative image would be restricted to dark graphite with only subtle hints of color. This shows metaphorically how a world can change and a sense of draining the joy and admiration you had for a person when they change how you view them drastically.

Irony: Dramatic irony- I know something you don't know.
Watching two characters individually in a series then meet and have a connection over an event. Perhaps character B stole character A's wallet, and we watch character A be unaware of it. Two color schemes for the two characters in which are combined when the characters meet.
Or it could be a situation in which they didn't do something to one another but share different beliefs. Character A could be protesting abortion, character B could have just had an abortion, but when they meet they are friendly toward one another. Shows irony and how public knowledge can create enemies more than privacy.

Emotional juxtaposition: An unnatural pairing, how humans can feel out of place with other humans due to personalities or events. To feel you do not belong.
Drawings in which one character is in graphite while the others are in color in various environments. The lack of color is a metaphor for how a person feels they do not belong because they lack something that the others have- brains, money, beauty, power, preferences, etc., shows how you feel like you stand out and the spot light is on you internally, but outwardly there isn't necessarily a physical , visible difference.

Memory: Memory distortions, repressions, how terrible our memory actually is.
Blurred motion photography in black and white. Same scene reenacted with different details changing about it. One a gun is present, one is not. One two people are present, one three are. One a vase of flowers is on the table, one is not. Etc

Morality: Why are some people black and white? What about grey area? How much is too much?
Figures of power who are supposed to be morally sound- doctors, police men, lawyers, politicians, drawn in both black and white India ink then again in blurred grey tones from generals wash. The color represents their moral strength compared to their moral appearance.

Myth: A false story you want to believe. For comfort.
Watercolors of children's bed time stories revolving around comfort from emotional or physical protection. Dream like state in a pastel, surreal world. Bringing the characters to life in the child's room.

Pastiche: "I was paying hommage to my heros" -Morell
Can the idea of inspiration or paying homage be represented through the act of. Recreating work that was done by ones idols? For example learning to walk a mile in. Gregory Crewdson's shoes through high production digital photographs, black and white landscape photos of Ansel Adams, or so on? Taking the theme and style of their work and time period into our own.

Politics: Two sides to every story, women's issues.
Side by side examples of visual symbols for why people would choose a side over a political reason. Drawings would be black and white and contained in a circle to show that their are two halves to a whole situation, a person can cycle through different opinions, and question whether they are homogeneous or different.

Power: King Lyre. Manipulation. "No one man should have all that power."
Visual symbols of monarch subtly introduced to the modern world, as a juxtaposition but continuum of power throughout time, with embedded text from King Lyre. The same power struggle situations they struggled with would be depicted with modern figures with chalk pastel.

Propaganda: Art with a purpose. Is art being taken advantage of?
Art as political propaganda. Perhaps show beautiful drawings, photographs, or collages without the text of advertisements over it. Get people to think about the work that went behind just the art featured in an advertisement, and how it is overlooked because of the text directing it toward advertising. Photography into magazine spreads via photoshop.

Pseudo-Individuality: Are you ever free of influences? Even through you might try as hard as you can? Identity is created in a ripple effect.
Drawing unique figures who have similar backgrounds. Represent this by drawing them over a collage of things that they have in common (Bible verses, same books they've read, movies they seen, lyrics they know) to show that people are produced by their surroundings, it only matteres what they take from it. Graphite drawings to show the universality among individuals.

Repression: To choose to forget, body defense, protection, automatic. Actively bury.
3D Boxes filled with envelopes and items along a similar theme.
Drawing a wooden box being buried, a box sinking into deep water, hiding under floor boards, or underneath a pile. Bold medium necessary to stand out and make an interesting geometric composition, like acrylic with strong lighting. Metaphor for what people try to keep in little boxes inside their minds by compartmentalizing and repressing.

Ritual: OCD rituals, calming, an act of prevention even if it doesn't make sense.
Multiple still life obsessions in charcoal showing either process or before and after. For example, seven (small) images of a person touching a door knob seven times replicated perfectly. Or, a fork angled next to a plate vs. a fork aligned perfectly vertical. Crisp, clean, black and white to show the dull, mundane repetition and need for order.

Social Justice
Basing something off of the "Innocent Project" (Freeing people from prison who were falsely committed for a crime they did not commit thanks to new DNA testing) and the people's assigned prison numbers. Perhaps integrating webbing over numbers and text then drawing a black and white portrait on top of it with generals wash or ink. It represents the chaos and frustration, the long process it takes, and references to the inner biological structures of DNA and body fluids.

Transformation: Constant, time, relapse, cycle. Can someone actually change? What it is like to go from one extreme to the other.
Not knowing which way it began  Having a person being boldly represented in color on one end as free and happy, while on the other end grey and lonely and not under their own control. On sand paper to show that transition is not smooth, but it is rough and hard. This also allows for the different amounts of colored chalk placed on it.
