nice avatar! ^^ looks kinda mortal kombat-ish ;D
the detail version is much better than the preview, i would suggest changing the preview aswell, because that actually is what ppl see as ur avatar.....
also i think this could be a nice anti alias excersize for u, since its still a little jaggy now... also anti alias is somewhat important to be able of...
i made an quick edit for u ;D .....
This is very good style! I think this is so far best work from you! I hope you make more cool pixels.
I like It ^^
Remind me for Mortal Kombat :P
