Progress Work: A concept sketch of Superman

Ok so this weekend has been pretty boring. I decided it was time to refine my drawing skills. I managed to get a concept sketch of our Michael Jackson Superman and a Tim Hortons uniform sketch done. The uniform sketch came out well as it just outlines one look we could use for our coffee guy. The superman sketch was a bit rusty, I guess I should keep practicing, its not good enough until the face just looks scary enough :) (Click to enlarge)
