Carter you probably have the most sound swing on the team, the one thing I would point out it is we do not want our hands to ever stop moving, the swing is a sequence of movements, we never want our hands to stall.  So when you watch your swing above you can see there are a couple frames where your hands stop moving and hang out by your shoulder.  When our hands stop moving they sometimes want to find something to do so they can drop or push towards the ball, which we dont want.  I would suggest creating a slightly bigger load with your hands or simply start it later so that the hands never stop moving.  If you watch some of the loads below you can get a good idea of what I am talking about.
