Great stuff. Really feel like I would be able to recognise you if I saw you in a mall or something. My only suggestion would be that hte AA is a bit lacking on the right side(our right) of hsi face.
This works really well. It's unique and very readable. The wave thing complements well with the strong directional light and facial expression, seemingly implying thought or some state of emotion. Only nagging question is, why no shirt? Despite the nag question, having no shirt makes it simpler and a differently styled portrait.
People are probably gonna bother you with reference here, although I never really care to see people's ref.
TCG?
Cheers for the comments.
@Mathias: TCG = Trading Card Game. I could say there's no shirt because it's been hot as hell here for far too long ;), but also I think it adds more visual interest and pushes the eye up to the *ting!* coming out of the forehead. But honestly, I just did it without thinking too much about it.
@crab2selout.png: cheers, hmm interesting you note AA; I was actually thinking I was coming close to over-AAing that area :). Oh and malls are the Enemy.
