His legs are huge! I understand you're trying to take foreshortening into consideration, but they'd still be much smaller. Also, it doesn't seem as though his right (our left) leg connects to the hip. I also think you should put more contrast on the skintones, use them more sparingly. You're using loads and dithering them so it looks really grainy and smooth. Try just cell-shading him and adding some dither later, to make sure you get all the muscle shapes defined. (deltoids should definitely cut out more, and I don't think a highlight on the pecs would hurt either
).
He looks chubby now, but he's the god of gods, so he should be more angular, his features should be sharper and bold.
Good luck!
edit: from your old avatar, and now your new one, I can tell you're great with ambient lighting. Some vivid complementary lighting could make the scene look more epic & godly.
