Hi rach,
The recording is hard to hear, as you've said, so it's hard to offer suggestions. Having said that, here's what I would suggest:
More clarity and accuracy. I know it could be the recording, but I hear murky stuff instead of the notes in some of the fast RH runs. Maybe less pedal? Practice slowly a lot.
In the middle section, you need to emphasize the melody and not so much the rhythm of the bass. Think "over bar lines" and long melody line.
The coda sounds muddy and again, more clarity is needed, the very last chord sounds too loud. It is marked, I think, pp or ppp?
Not to be too critical (This piece is HARD.)--You play with a lot of feeling! Keep up the good work, and Have fun!
