Get a little more weight forward at impact. Your slightly spinning you hips to fast, instead of getting a lateral shift with your hips. This is causing you to loose the wrist hinge to early in the downswing. I paused it were your clubhead was around your right foot, and it was inline with your arm to your shoulder, that position needs to be at impact.
So, more weight forward, and hands inline with clubhead and shoulder at impact. Try to maintain a bit more flex in your left leg through impact.
Check out the 5 keys video thread, and look videos relating to flat left wrist and weight forward.
Couldn't tell much from the backswing, but your head doesn't move much, and you get a good rotation with the hips. So things look good, just need to sure up a few things.
