A good start! What’s missing (I think) is some secondary motion in the flesh, and some flex in between the body parts.
You can get secondary motion in the flesh (even if you don’t intend to record back to it) by assigning to some additional objects around the body, representing flesh. This can help add some softness and momentum to the fall and to hitting the ground.
Not having any softness inbetween limbs can also make the character seem like it’s a miniature plastic action figure. Having limbs slightly stretch and compress can help make it seem more natural. Again, even if your original character cannot actually translate the controls. The feeling of it is preserved in the overall rotations too.
Here’s some examples.
