Nice swing for being 3 months into the game
Yes you have early extension, you seem to push off your toes when turning lateral with your hip. This causes a forward thrust and your shoulders hang back in an out to in swing path.
Look at your right foot and knee at how they point to the right of your target
Some tips/tricks to to work on :
- Straight left leg when starting lateral hip movement
- Roll right leg and ankle toward target, causing you to push off on the side of your right foot
- Keep eyes focused on ball as long as you can even after impact, head will sway a bit on the back swing, this is normal
Hope this helps!
