Looks short and sweet. Is she making a lot of contact? If so, work on getting more top/bottom seperation before launch. I like to see more weight transfer(getin' off that back foot and into the ball). If she doesnt make a lot of contact keep what you have and work on hand/eye(front toss, p-machine work). Keep up the good work and have fun!
