:), it's supposed to be a mole of some kind. Now that you mention it, it probably is the least readable of the four. I'm looking into using these sprites in a game so readability is very important. Thanks!

I'm completely blow away by this. I guess I shouldn't be that surprised though, you're very very good.

It looks awesome, you should post more of your work on here. If you'd like help on anything I'd suggest you go to the forums on the WIP board. The people there are very nice and helpful.
