I think it looks great
The only real problem I see here is that you need to work a lot on your proportions. The bodies of your characters are really abnormal - legs constantly change size, torsos differ etc. You need to work on the anatomy of the human body in order to get it right.
But the rest was excellent! I especially liked how you used shadows - really impressive! Waterflame's tunes are always great to use in action scenes, too. I noticed a minor Madness influence sometimes which is always fun. And like people said before me, the frame-by-frame animation itself is superb. Overall, work on your anatomy and body proportions and you could be one of the big ones. Good work!
