Yeah, I agree with the size issue. I should blow it up a bit. I was also trying to convey the fact that he just barely escaped a mouse trap (his tail is all messed up), and so he's feeling all kinds of clever and mischevous, when, in fact, his brain is the size of a thumbtack.
his back is drawn as though he is sneaking with it pressed up against the wall...perhaps there should be a wall, or the mouse should be placed on the shirt so that the left side of the shirt becomes the wall he is leaning against. other than that, totally cute.
