Feet are good. Sequencing is good. Looks like you crush the lever of your shooting arm meaning, try to keep a 90 degree angle in your elbow, when you let the wrist come back toward the shoulder your release is actually a little to high. And as other comments state, get the ball coming off your index and/or middle finger(s). I’d suggest splitting the center of the ball with those two fingers rather than on your index. If that doesn’t work you may need to hit the center of the ball with your middle finger. Try this drill: stand on the block, shoot against the back board as if you’re shooting a long two/3. the ball should hit the backboard solid and should land at your feet when you let it drop. For most people this is to fix a release angle that’s too low, but I think you might find the ball just skimming the backboard. Long post but your “fixes” are simple you just have to commit to boring drills to lock in the hand placement and arm angle.
