Underlying anatomy problems are the same with your past work, I think. The color selection is interesting, but the pixelling leaves a lot to be desired. It looks unrefined, more than anything. I'd start by tightening the anatomy and the forms would follow, probably. His hips are as wide as his shoulders, are you sure you really want this? The arm is like spaghetti (remember that crit the BOB gave you?) the right shoulder is rounded like a beachball, this just doesn't happen. The neck is not in the middle of the shoulders. You put more effort into the legs and that shows, they're much better, but you really do have to hit the anatomy books, still.
