Well, a while ago I was sitting around, bored, and started to draw some random expressions. Well, whitout really looking at the quality or something like that =P

From left to right, top to bottom:
Angry
hm... surprised?
skeptical (the first one I drew, in a session)
confused
hmmm... disappointed
dont really know what that could be (second row, last one on the right)
... is about to puke ...
silly
annoyed - the "oh... really... " face hehe
world domination (MWAHAHAHAHA!!)
warning - drama!
dead... or maybe just sleeping =P

Well, anyway, like you maybe already could see, I did the one on bottom left on paper, yesterday - somehow I'm in the mood to draw silly faces...
