Great!!! You have a great touch for Beethoven. Around 3:35 you got a little unclear, and from there until the end I got the feeling you were rushing it a little bit (I understand the urge to do this in such a piece!). Some clarity and rhythmic consistency got lost toward the end. So I would take out the coda and work on not speeding up and keeping it very clear and strict rhythmically.
Those are picky comments--You play this REALLY well!
Ok, on a very high level i would improve two things:
1. Brilliance (maybe you can decrease the tempo a little) 2. Intensity (those ff's in the beginning and in the coda were way too soft, also please play the repetition in the coda)
Judging from your recording you should be able to apply this in very short time, good work.
Same with Chopin Etude Op.25 No.1, at the beginning I recorded this only for myself, for analyzing purpose and all were taken in one shoot without exercise etc (Cold play in the morning). But after listening several times, It makes me want to share and get "real" input/ feedback from outside, especially from great forum here. And I got those feedback ! thanks a lot ! Looking forward for another comments etc
