Don't really like the back extension at the top of the backswing which is leading you to lean forward with your upper body. Then your lower body has virtually no participation in power development and your leg action shows it. There is no leg or hip drive because your weight is already leaned to the left.
Get rid of the target-ward extension at the top of your backswing and drive the right leg forward ASAP. Try to get your right knee to brush your left before impact. That way you get your weigh to the left foot but it's the lower body that makes the transition happen instead of the upper body.
