I added a couple layers of oil paint. First I glazed in alizarin crimson and phthalo blue to give the face some color. Then I started laying in thicker, tinted versions of those same colors with paynes gray. I like to lay in the oils a little messy, then clean it up with pencil. It's drying in the back window of my car as I write. I also added a white glow behind his head with white oils, then scratched in a little message, "I will BURN you."
