Your release looks okay to me. Don't resist the backward motion of the elbow, just let it fly back naturally.
You seem to be raising your shoulders up during the draw, kind of like a shrugging the shoulder motion, which can lead to pinched neck muscles if you shoot a lot. Use your lat muscles to keep your shoulders down.
Your top limb jerks suddenly forward and seems to pivot around your grip. I'm not sure if that's a result of you adding torque by gripping at release.
Lastly, in the shirtless videos, your upper body is kind of leaning away from the bow. In the other videos it doesn't look like you're doing that. But make sure you lean into it. It mentally sets the mind toward the target, which is where you want it.
