It does look neat =D Though I agree, the chin is distracting (it looks like a little brain)
The pallete could be more interesting, and the shadow on the forehead slightly darker? Also, the 50-50 dither patch, while not immediately noticeable, bothers me now that I've caught it (because there is none such dithering elsewhere in the pic).
It is very fun, and the border is eternally cool (except the incongruous curvy part at the bottom, since the rest of it is angular)
P.S. I just noticed his cross tatoo doesn't really curve around his forehead, which adds to the impression of flatness.
P.P.S. I love the texture of HIS right cheek.
