Get a huge piece of plexy glass or glass and dry erase markers. Then set up a camera and take self portraits w/ me drawing my feelings over my face. Or some type of alterations to my image. Or try to make myself look like a child.
Repeat the process and have my friends come over for their portraits taken, with me doing the plexy glass illustrations and image alterations.
