I'm not really into chopin, but this is one of the few etudes of his that I really like, and you play it great. It has that lighthearted feel throughout and is enjoyable from start to finish.
The two things I would do differently
1 - I'd play the left hand chords with staccato dots, for example right at the beginning, a bit sharper and shorter, otherwise they feel too flat in my opinion.
2 - Keep up the ff at the end, maybe even cresc. towards the last chord/octave at the end. I think otherwise it is kind of anticlimatic, because you build up with the descending octaves, and then suddenly the intensity drops at the end. Keeping up ff also creates a better contrast to the beautiful lyrical section right before it.
Btw, the reason you couldn't upload it here is not the filesize but the format, because .wav is not allowed.
Anyway, you played great. Keep up the good work!
