Well done! It's a challenging piece, is it not? How do your hands and arms feel after playing it?
Your playing is terrific, man.I feel a bit embarrassed to give any other feedback than that, but since you're asking: what I would wish for is perhaps more brilliance in the treble. Sometimes it sounds a bit bland at the top of each 'wave'. Maybe you need to be even freer, moving the torso and arm along to transfer more power to the hand when it goes up. How long have you been playing this and how old are you? I bet you'll be second to none in this piece if you give it more time.
Although Chopin indicates F or FF most of the time, with some crescendos (and decrescendos), to play it as written dynamically - can sound a bit monotone.Try adding more nuance to the dynamics, and think as if you are telling a story, and where a bit more dramatic fluctuation could enhance a passage.Very slight tempo modifications - (like a hair slower in some spots - like at cadences, or, ) - could add a nice ebb to the rhythmical aspect, and mitigate it just sounding like an exercise.
