So many ways of suicide, wonder which one to choose... Looks to me like you beheaded yourself. As if your arm is the hangman's axe. Or maybe it's the different hues of of the skin that make your head look somewhat disembodied. There's really something mad about the deep shadow of your eyes, and your hair looks like it dissolves into the wall.
I have set aside one room in my house to be my shooting room. It has a smallish, slightly elevated window that provides excellent light, is filled with my trinkets and props, and has a wall that I paint and repaint as a background.
I do all my work in there.
