Hi Craig, looks like you are getting a lot of really good instruction here. The main thing that everyone keeps coming back to is you are collapsing at the shot. This is a very difficult thing to explain, but there may be a way for you to fix it. When you can get this fixed, your release will fix itself. Do this. Pick a spot on the target and pull your bow up with your bow arm as if you were getting ready to draw on it. Don't draw your bow, just pick up your arm. Now, look where your bow arm shoulder is at. Chances are it is pointing to the left of where you are looking at on the target. Now move your shoulder into position until it is lined up with your bow and that spot on the target. This is where your shoulder needs to be when you are at full draw. Trust me, I've had this problem too. This is why you are shooting left all the time. You are not fully extended, and your alignment is off. When you release, your bow arm jerks to the left. If you can get this allignment problem corrected, your release will fix itself, and you will have less muscle strain. The shot will feel much better and you will enjoy shooting your bow more.
