Remember, we have a great group of members here, before posting a piece to the gallery, you can always post it to the WIP section. Everyone will help you out with Critiques and Comments to help you get the piece to a much better end result? Great attempt tho, it looks like you have a great style it just needs some refinement.
I think it's a nifty character, but it seems very messily done. I mean, the scrappyness is an interesting style, yet i see the outer AA and outline is very odd, and leaves it sorta jaggedy. I'd AA down the thick line with the next lightest colour. Perhaps give the teeth some shading aswel? Wh00t.
