Drawing on the iPad, well, it's better than trying to draw on a small screen (like that of a phone), but without using a stylus, it's difficult to do detail work.
Draw Something, for those who don't know, is a turn-based Pictionary type of game you play with people over the internet. It only has 4 brush sizes and you start off with a limited palette of colours, and can unlock colour packs the more you play. So yeah, most of these aren't much more than doodles, though I'm quite happy with a few, given the limitations. I've rearranged the OP to show off the better ones. :P
