OK, now I can say that your draw is too long. About an inch + whatever the length of the string loop. You can still shorten the release, and a recommend it. Also get the string loop shortened up It only needs to be long enough so the release jaws don't hit your nocks.

It's hard to sit and pick apart somebody's form and say change this and change that. Doing everything at one time really throws a guy off. Change what you can for now, and feel fairly comfortable with. Do things in stages, giving your muscles time to adjust to those changes. Then move onto something else.
