I couldbe wrong -
Last vid, thing that jumped out to me is the way the bow hand seems to be way too deep and broken back. Leads me to feel that you're not push / pulling like I think you should. I try and use the heel of my thumb as a presure point on the bow to help minimize tiller influence with the bow hand.
All vids, release looks forced (as mentioned). Again this looks like push / pull issues.
Don't force or control the release. Simply let it happen.
Moot point, but the stance looks a bit more open than I'd feel comfortable with. May not be a issue for you though.
Also, using the pause / play on the second vid,,, you're really throwing your bow to the left on release. not so good. (push/pull)
You really like that glove? Looks like you're shaking off the pain at the end of every release.
