Please keep in mind; the way you have the hands in rest position, that is incorrect. The fingers don't curl in that much. The best way to test if you have it right is to put your own hands exactly as your character's and see how his hands must feel. If you do what he's doing with his hands they are very stiff. If you're going to keep them like that puff out his arms and chest a bit more. Thought you may like critique.
