After this there's nothing left to do but shoot. Remember once you release the ball, you're job isn't done. You have to follow through. It means that your arm should be all the way up, your fingertips pointing towards the basket as if they were going over the rim and through the basket. Once you have practiced proper technique then you must practice shooting on a daily basis.
Shooting is based on rhythm.
The more you practice the routine the better the rhythm and better you will become. When I practice dribbling I start out with something very simple. First, I start dribbling in place with my right hand. Then I change hands and do the same thing with my left. It is important to make your left as strong your right so you can dribble with both hands in either direction.
