Inspiration for Self-Portrait

It took me awhile to think of ideas for the Self-Portrait assignment, but I think I have finally come up with an idea. I would somehow like to represent the past and the present, which in turn would be showing split personalities. I just recently went through some tough times in the past, and I would like to represent coming out of darkness and going into light; going through a bad time, and coming into the light/future. One side of the portrait will represent darkness, and I will do this by showing darker, colder images. The other side will represent happiness, lightness, and hopefullness, which is a portrayal of a hopeful future. I will incorporate personal images that give me hope, and make me feel better in hard times.
