Out of interest, how long have you been practicing this piece - in terms of days and hours per day?
Quite a lot for such a short piece.
I think Chopin etudes deserve a lot of time and to play it as great as you did is absolutely worth many hours of practice. ...And which one is your favorite?
Wonderful job! So glad to see another person who loves music so much. Which etude next? I love Op.10 no.6
That's very impressive. I second all the positive comments. If I had a suggestion, it would be this. The piece sounds a bit rushed. Not that the tempo is too fast, but I get the feeling that you are just the least bit early when finishing one phrase and going on to the next. Not that there should be a big pause, of course, but I think you are slightly shortening the last notes of many of the phrases and that gives a rushed, uneven feel at some points.
