I think you are generating too much power from your arm, and you are leaning into the ball instead of generating up from the lower body. Try loading with a bigger shoulder tilt, drop and rotate the back hip, and aim for about 60 40 or 70 30 weight on the back foot. Also, keep the strings facing down rather than up to help pronation and avoid locking the shoulder. I suggest working one thing at a time, and I would appreciate it if anyone watching supports the video."}
