You learnt this in the last week of 2020... Impressive!
Wow! You play with admirable flow, lightness and clarity. Very enjoyable, looking forward to more posts.
Very impressive. I think you nailed the character of the Etude. The only thing that bothers me is that you play the last chords kind of softly, while Chopin marks them FF in the score (I checked my Urtext just to be sure). I think they have to be played in a more strong, firm manner, like a final, solidifying statement.
