Hi Brian, you're looking darned good overall. If your arrows are hitting well then be careful about making many/big changes (the 'if it ain't broke don't fix it' thing). Sometimes even little tweaks can bite you. Still, it's fun playing around the edges.
At first glance I'd second Ajooter's comment about moving your head at release...it's a very slight movement but your head line does pull away to the left a little, which I suppose might affect your bow arm or alignment. But, comparing this most recent video with your past Wesley video shows that the slight head movement is consistent from shot to shot...so it might just be part of your natural style. Again, the important thing is where your arrows hit, not copying what someone else finds to be effective. We're all built different...thank gawd.
PS Found a nice home for the Wesley (hated selling that one), but picked up a nice little Dwyer Original (about 7 pounds lighter) that feels great to draw, and it drives tacks. My shoulder is smiling.
Stay well, bud.
