When you bring your feet together, your chest and hips face the back, so you do not open the hips into the court, which makes it hard to coil and generate power. I suggest keeping the back hip rotating so it stays facing the back fence, and keeping your left hand from opening your shoulders too early. Your racket drop is good, and your pronation is good, but at contact you need shoulder internal rotation to accelerate through the point. I asked you to work on one thing at a time."}
