Maybe I'm to picky, but it looks like you have your weight mainly on your front foot. Try distributing your weight evenly and see if that helps steady your stance. Other than that I agree about the release arm. Forearm needs to drop flat(parrallel). The way your wrist is bentit may be that your bow isn't set to the right draw lenght. Should be ableto draw back and relax your arm holding the weight of thedraw with your shoulders.

Just me observation.
