Great and all but it seems odd that you choose to make the pivot point for the action in her knees... when it seems like it should be at the ankle. it would be different if the guy was the source of Force acting on her but she is the source of Force...... so ideally she would need more leverage for the action shown to be plausible when considering her center of gravity..... but i may be wrong. Reference video would come in handy here to know for sure.
i mean i have a feeling the reason you made this decision was so you didn't have to redraw her entire leg each frame.
which is fine. Animation is very Time consuming.
in reality it doesn't bother me that much... this is literally the only criticism i have.
just felt it was something good to keep in mind.
keep up the great work!
