What Bowman said. I also noticed that in the straight on shot after you settle in you released all but your thumb and index fingers on the grip, they next shot you left your hand closed around the grip and then on the following shot you opened your hand again. I would say the grip is your issue, get the sling and then make it the same every time. You shouldn't hold the handle of the bow, use your grip hand as a brace to pull back on. Your draw may be about 1/2 inch too long as well. It appeared that the string is coming back past your nose. That may have been camera angle as well?
