Hi Pianistimo,
I'm certainly not anyone to be giving advice here yet, but regarding the middle section, I think you could vary more the dynamic in the left hand and interrupt the medal more often between bars. I think it might be blending a bit too much.
As for the rest, I'm sorry but I don't know enough to comment, even though I also play this piece.
I have a question regarding the recording, though. It seems to me you're recording in Mono. What setup are you using?
