Normally I would say the hands are to far behind the back foot. She seems to make it work, but most elite hitters have the hands directly above the back foot.
Couple of things:
1) I'd like to see her use her upper back more (elbow somebody behind you).
2) The position of her hands at launch is too far back imo. Should be nearer to being over her back foot
Both of these things is causing her to push and be too steep to the ball
You posted while I was writing mine, we see the same thing at launch with the hands.
