Just a stylized version of Harry, Draco, Ron, and Hermione. I really REALLY like Ron in this picture. I decided to give Harry all dark clothes, 'cause I think it suits him. Hermione went through a few phases. At first I gave her a buttoned-down, bookish kinda thing. Eventually I decided to give her a liberal sort of attitude. I thought it might work. She has a rebelious, free-speech side to her that comes out in house-elf issues, and such.
