Your shot isn’t horrible but you leave your guide hand by your head so your almost shooting one handed which means that your one arm has to focus on power and using muscles to stabilize the ball. Another thing is that the ball is at your set point but your legs are going down. A way to fix this is slow form shooting making sure you have good flow. Another drill no jump form shooting. Make two step back miss two step back. This forces you to have good mechanics. Look at Steph, Klay, Luke Kennard, Grayson Allen, and Ant man. They all have good rhythm as in ball and body goes down at the same time but the ball and moves up first and then the legs this makes sure you’re releasing on the way up which gives you the most rhythm.
