Great work!

But this need some correction, in my opinion.

See on his legs, you forget about form of calf on his leg. Ir's look strange. I quick edit you characters, see it maybe this help you.
Man - fix legs and shoulder (In my opinion he is the best from other

). Girl - Right hand is too long. Legs not on surface and proportions of thigh and calf is wrong. It's just edit you may do this more better.

And this too trouble with legs (look like a hose) and trouble with his left hand - she is very small and strange position.

There just legs
The broken extremity very distinctly on your animation for each person.
And a bit comment. This kick is not to do with heel, because this is may broke you achilles' sinew and will be a invalid for all live )) For this kick striking surface is footstep with a bit elongate toe.
Anyway you do a good job.
