Play with more rubato and let the piece flow more. At the moment, (and this could be because you're still working on it,) it feels choppy. This is Chopin, feel free to let the piece breathe. At the moment, it doesn't feel like Chopin. Listen to recordings and that will help you understand the nature of his compositions better. Of course, I understand that you are still working to perfect this, and it will be much easier to make it flow once you have the piece better under your hands.
I would also agree with Noam- the bottom notes are sometimes louder than the others, which is distracting. They should be only an audible countermelody (if that's right). They sometimes overcome the main melody, which shouldn't happen. It sounds sometimes as if you are pounding the bottom notes, which was never Chopin's intention.
The tempo marking for this piece is 132, and I believe you're playing somewhere around 95-105. Nobody actually plays up to 132, but the piece sounds its best (in my opinion) up towards 118-125. It takes a lot of practice to get the piece to that speed without sacrificing touch and phrasing.
Another note- your trills need work. Chopin's trills need to be played fully. Listen to a recording to hear this. Those embellishments are VERY important and not to be forgotten under any circumstances. Such is also so with Bach. They MUST be executed properly. Just a matter of practice!
There is some hesitation on some of the more difficult passages. This is just a matter of practice,
May I suggest using the left pedal? It will help. ALTHOUGH. Only start using it once you have refined your touch without it. Don't rely on the pedal.
Overall, Good job on a challenging piece! Feel free to ask me any questions that you have as I just finished working on this as well.
