after listening to it again i think you should definitely make HUGE dynamic contrasts because it seemed flat throughout, and also phrase with dynamics to give it more movement. definitely make the soft sections much softer, that would make it far more interesting. as far as what i said about the transition phrase at 1:37 since its completely different from the rest of the piece it should be given more thought if u know what i mean--maybe a slight ritard or just try not to rush it because it seemed a little rushed. anything else that i would say would probably just be personal stylistic preferences and i dont really know the piece that well to critique it more specifically. great smoothness of technique and the melody was brought out pretty well too. also i guess since it is romantic and Chopin you could create even more interest by adding rubato and expression into phrases, but not overdone.. just enough.
hope this helps >.<
