Wonderful playing! You definitely have a natural inclination towards beauty. Personally, I believe that critiquing unfinished work is a poor idea, so I'll postpone any thoughts I have until you have the whole work finished/polished. In my humble opinion, I think you should abstain from using your age as a device to prevent any frank criticism. You're a very high-level musician, not just for a thirteen-year-old, but for someone of any age. That being said, you know the cliche saying: " With great power, comes great responsibility. " You have a wonderful musical mind, and all of us here at PS expect you to keep using it for the highest achievements. Personally, I would be inclined to critique your work in a more straightforward manner than a lot of other people's recordings, because I find your potential to be so high. Wear harsh criticism as a badge of honor, a lot of the time it means that people think you can process the ideas maturely and apply them in a wonderful way. Of course, some people just like to put others down. But you're a smart person, I'm sure you'll be able to separate the wheat from the chaff. Keep up the great work! I can't wait to hear more from you.
Best,
AJ
