Liked the idea of it.
Body proportions are off, I get that it's manga style but you still need to care for the basics. Lower legs are too long/ thighs too short, weird thumb on right hand. Pose are too stiff for such a dynamic concept. Hair, scarf, skirt and tie(?) flows the wrong way, if she's falling downwards everything I mentioned should move upwards.
I suggest find some reference and do an anatomy study.
