Imo what you do at about frame 180 is a problem.
you get into a really difficult position resulting in that sloppy dm.
the second hit looks much better but then again theres this unbalanced pose.

I say from that lying on your back position you cant do a good hit. if you just kick it looks limp. if you speed up with your shoulder you miss.
so I would change how you fall so you can actually make a powerful and precise kick by raising your shoulder.
