Excellent work on this very advanced piece. This is a great competition piece for someone your age and you are off to a great start.

You play very accurately. That is a huge challenge and you have met it beautifully.

I would like you to work on adding more wrists and playing your LH softer.

Make a practice chart that includes:
3x RH alone every day focusing just on wrists

1x watching my response video

1x LH alone ghosting

1x HT with LH ghosting, RH with wrists
