Your shot sequence looks very good to me. I'm not a coach nor am I a great shot, but I really try to focus on proper form. That said, I'll offer my insights.
One small observation I have is that on the second shot, it appears that you collapse slightly before the shot. Watch where the bow string rides alongside your nose when you come to anchor. Just prior to your release the string comes forward slightly. Also on the last shot, you actually let the string forward noticably then pull it back to anchor before releasing.
Arne and Rod Jenkins always say that if you have a hiccup like that, and we all do, let down and reset your shot. That's harder said than done. One thing I try to remind myself during shooting sessions is what Rod say: "you cannot shoot too strong a shot." In other words, pull back strong to anchor and keep pulling hard.
Hope this helps,
Dennis
