Did you perhaps trace these from a 3D models animation or some of them anyway? They seem very very slow, like molasses slow.(no offense) There are just too many frames and it kills the fast action you were going for. Especially the 3 hit attack. The first elbow strikes image blur looks like off because of how sharp it is, it feels like it lingers there too long. Originally I thought you did the image blur before the actual strike in order to better cover up the distance covered but that doesn't appear to be the case. Heres a good example of how to do image blurs if only because it looks and feels "right"
If you didn't trace a 3D model or a person or used a guide you copied from or what have youI would love to train under you as an apprentice because I've never seen animation that smooth especially in pixel by hand.
