We have been working on some of the suggestions. Please let me know what you think.
She's improving. Keep it up.
A couple of things. NEVER let the head get over/above the front foot. It should stay between the feet. She hits the ball then drifts forward. Even though this occurs after she hits the ball, it's an indication that she is not bracing the front side enough and is pushing sideways to much.
The front leg must stop all forward momentum so that rotation occurs. The back foot should not drag forward like her's does. She should end up on the back foot after the hit. Like the guys below:
Also, during the hand load, the rear elbow should get behind her back more, and the hands should be farther back and closer to the armpit.
