Jerking the release as well coug, squeeze that trigger.

I agree, Squeeze the trigger don't pull, this will cause your bow to pull along with it. Also I noticedit looks likeyou have a death grip on your bow just relax your grip maybe open your hand a little. When you grip tightly on your bow this can cause you to sometimes tweak your bow a little causing inconsistencies in your shooting.

Aw, heck I see what the problem is; you're shooting with the wrong hand![8D]

I noticed you punching the trigger in the second shot as well. Also agree on the sky pulling as well. Try to keep the bow pointed straight down range and pull straight back, you'll get busted a lot less if you can do that. I've drawon my bow with deer looking straight at me by doing this because all of the movement is slow and straight back.
