Capt. Dave,
Looks like a nice stable shot. Good follow through.
The only thing I would suggest is as you come to full draw, you are drawing slightly under your final anchor point (WHICH IS CORRECT!). Then though, as you elevate to your final anchor, you let your string hand move slightly forward to final position. Try to move straight up to anchor NOT FORWARD. That slight forward movement takes tension out of your back. You have a good string hand follow through but I think it would be better yet if you could get rid of that small forward motion.
This suggestion is meant to help with the increasing tension you want in your back and to prevent an occasional collapse that is often caused by decreasing tension.
Overall you look very good and really do have the basics well in hand.
