It needs easing? I don't think so,it isn't a rush,either,its an improvement.
Well it does need some more easing but your problem is the speed, your fps is way to high for that fast of movements, I couldn't keep up with it at all, I would say either add in between frames or lower your fps until you practice more and can manage a higher one. Also what helps emphasize hits is double framing on them, I would try that too. Not bad though :)
EDIT: ok, so I went through and frame by framed it. You double framed ALOT in it. you need to add a lot of in-between frames before each hit. that will help you improve the jerkiness of it and add a smoother feel. :3
