|Setup, posture and foundation are good. Fundamentals, alignment and swing plane are all very good, but you need to look at these issues:
1. With driver, your arms need to be further away from your body in the setup, will give you a more rounded feeling with the driver during your swing, and help stop the out to in path that can result in a pull or a slice.
2. Right arm needs to be more relaxed, so it can fold and rotate during the takeaway.
3. In your backswing, you need to make sure you maintain your spine angle as you take the golf club back.
Good luck with your golf.
