Ah, well that would explain it. Add some more dark brushes over the lighted part and it would look better.
Excellent design though I have to agree with the comments about the overlay on the face and it seeming just a bit empty. I think some text (name) would fix that issue. 8.5/10
8/10. It would get a 9 if it had text (but I see what you said about personalizing it). Branded it with something like "New York's Captain" or something would look really cool.
