Very solid overall. Based on how good it looks I would say you should look at some stretching exorcises so that you can get a better rotation of your shoulders. Your rotation is better than probably 80% of golfers, but it's something you could improve on without really messing with your swing.
Look at Tiger here.
Tiger Swing
He gets his back pointed to the target, hell maybe even past it. You'll probably never get to that point but compare with your driver. Stretching will help you get more rotation and it's something many golfers don't even think about. I really don't think you should mess with your swing unless there is something wrong with how you hit the ball.
