really like this challenge so i just had to participate; might make the others aswell; unsure about that.
Yeah, I like the lighting on the face as well. The eye could look more 'evil' - perhaps wtih a dark outside and a lighter inside, it would look less like an alien and more malicious. Anyway, it's cool!
hehe at first I thought it was a ninja.
nice style, and the lighting on the face is really well done.
