Head moves too far up and to the right. Part of it is just the way you address the ball.
- Need to get the handle higher, point the butt of the club closer to the top of your zipper
- Allow the head to "hang", lower the eyes

Good Golf Posture
So the head moves too much which causes the shoulders to turn too flat and the left shoulder to travel too far back. This is going to cause some path and sequencing issues.
Note how the left shoulder (below) goes down and back, to about the center of the stance.
Some good drills to help you keep things more centered. The eyes being more down at address will also help, the left shoulder won't be able to go so far back.
