This is pretty good animation for the most part but you missed the title word - balance. She's swaying side to side like she was hanging downwards but doing a handstand she'd just fall over like that.
She can sway but her center of mass must remain still, if her legs lean left her torso must lean right to compensate and so on.
I realize this isn't the intended focus of the piece but it's still what stood out the most for me.
