Shooting is a tough skill that takes a long time to perfect. The form must be perfect and be smooth. You should bend your knees and keep the knees pointed in. Your strong foot should be slightly in front of the weak foot. The ball should be on your finger tips and the palm should not be touching the ball. Your shoulder should be tucked against your body. Your weak hand should only hold the ball in place and guide the ball. Your strong hand should keep the ball over your head with the shoulder tucked still. Put the strength of your legs into your jump. Bring your hand straight up and release the ball from your hand. Most importantly, keep your hand up/follow through to make sure you shot correctly. Make sure you land on the ground exactly where you jumped up.
