Nice swing.
The tee is in the right spot. It should be at the ball of the front foot, after stride.
"any drills for that ?"
Always, always, make sure she is coiling INWARD as she goes forword to toe touch. Even though it could be better, she is doing this somewhat now. Make sure you dont do any drills that might break this.
I can try the hover drill and monitor that she keeps the inward coil (and keeps improving on it).
