This is pretty good, but I kind of feel like the style doesn't match internally. So, independently the parts are good, but the face seems way more realistic than the body and hand. The background is probably okay though. I think that maybe the color on the face could be a little warmer. That may lessen the problem a lot. I would also suggest redoing the hands, probably with reference. Not only are they more cartoony than the rest but the fist closer to the front seems contrary to the arm muscles. The arm seems to indicate that the hand should be vertical, whereas it is horizontal in this. The back hand also seems awkward in positioning. I'm not entirely sure what would fix it, but I do think that if the hand was angled away a bit more it would help. I like the texture on the suit, but I think you should also add some texture to the cape. Also, the highlights on the face seem a bit too plasticy, though I would understand if it is a style thing. Still, I would suggest adding a little bit of skin texture at least to the edges to take away some of that porcelain doll feeling. Besides that, I love the way the face looks, the action of the whole scene, the epic coloring and the general power of the piece.
