One of the things we're doing for college are these "Drawing Jams". Essentially, we take a real life reference and turn it into a drawing in a pre-selected stlye. The first of these required us to draw Tom Green in the style of Scott Pilgrim (the comic).
I have to say I was quite pleased that this was our first Drawing Jam theme, since I've been a fan of Scott Pilgrim and Bryan Lee O'Malley's since 2008.
