Overall really smooth for how high of a backswing you have there. But that much cupping of the wrist at the top would concern me when coupled with how far inside your hand is getting. That much motion can be damaging to your consistency. If just one thing is wrong at the top of your back swing everything will get off. I would try to get that figured out. That usually comes from some one trying to rev the cover off the ball at the bottom and it actually doesn't do much of anything except feel powerful and really mess you up when its off.
