These first three pictures are stills I took.
Here you are in your complete delivery
Here you can see your arm is getting up early. At this point your ball hand should be pointing straight down toward the ground. So, you want to hold, hold, hold until your body is ready to bring the arm up.
You can see here where your elbow is above your shoulder and your back foot is not quite peeled up enough. It is a tiny thing, but it makes a huge difference. You can also see your shoulders are in a V shape. At this point they should be opposite and equal.
