I find the fact that it looks like it has More than 3 Dimensions give it that edge that makes this more than just a good piece. the strong light and heavy shadows with a the dradients in between gives me a sense of mixed culture (asian/european mix).
the only thing i feel different about is the use of blur in some parts. the waist belt for instance, I fell was blurred a little more it should have or maid with a brush that was a little too soft. It looks like there was a lot of detail there that i may have missed out on because of it. and the really sharp, flat red characters aganst it establishes alot of contrast but it may be more contrast than need
I gotta ask you later about how you pulled off that great "darkness" effect.
