Excellenté. Only thing I'd change is possibly make the mouth slightly more subtle - it seems too black, with no softening around the edge....but i spose that's a matter of preference Also, what's with the weird squiggly texture thingy?? I think it kinda detracts from the image when you fullscreen.
P.S. Did you take inspiration for this from an M:TG card?? 'Cause for some reason it really reminds me of one (cant remember which though =S)
Amazing work. I really love the evil look on this guys face. I think he has been to my house recently because the only way I can use my computer is if I have it in safe mode. I think those guys are having a party inside my computer )
