Good morning 2bird,
Sorry I couldn't respond yesterday, was teaching a Level 1 instructor class out of town.
Here is what I see, but you are right, we really need better video angles and lighting.
Your bow hand appears to be too deep into the bow grip but again, the shadows make it hard to really see.
Next, watch closely and critically your string arm elbow as you reach full draw. Can you see it moving forward and back several times as you set anchor? That is disconnecting you from your back. As you draw try to concentrate on that elbow moving back,UP and then back again. NEVER forward!
Because of the loss of back tension, your follow through is an after thought. You see the release THEN you consciously move the hand/arm back, rather than that movement being a RESULT of the release -- a natural action not "play acted."
Actually the third shot is pretty natural, but not the first 2.
Hope that helps a little.
