Thanks. Agreed there's definitively something wrong in this sculpt. He is suppose to be a massive Pro Football Player but he is a bit the upper body is a bit oversize and would have benefits of a more dynamic pose.
I think the jacket is doing weird things around the waist. The material seems scooped in somehow, like it's being sucked into a hollow belly, in a way that cloth wouldn't hang. Also, the creases at the sides are oddly positioned, as though the body is twisting both to the left and to the right (if you know what I mean).
But again, your paintwork is absolutely bang on. I find it very difficult to paint black cloth, but you've absolutely nailed it.
