Some really nice details in there bol! like the details in the arm and how you've constructed it, those folds you've painted on the pants, and the painted texture on the jacket :] Great stuff as always!
Definitely some bad-assery going on here! Your digital painting skills never cease to amaze. There's a little depth confusion going on between his hand and the block he's sitting on; it almost looks like his hand is resting on it. Very minor so it doesn't hurt the overall image at all.
