Personally i think the right arm is angled wrong i mean i just tried to make that position with my actual arm and its not happening lol..., the right foot looks more like a flipper, the lightning looks more like u just scribbled some lines in the sky, the one lightning beam by his "strong hand" doesnt even connect to anywhere, and im assuming from your other work, i guess you need to learn that their is more to anatomy then just boobs. Not being a dick, just telling you how to improve as an artist...
