Kinda looks to me like the shading of the face and the body don't quite match. Not that either is done badly, but more of a closer to realisticly softer-shaded body, compared to a bit more flatly/sharper shaded face.
And I think the eight pack is a lil funny, only looks weird if you stare at em too much. But hey, One Piece got away with it. Or maybe I'm just too scrawny and don't know enough about muscles to know there are 2 more secret packs to unlock.
But deffinetly solid job on the hands. And overal, a sexy lookin dude.
