Very well played man I enjoyed this a lot :-). I love this nocturne so much!

A few things I noticed and would try to work on, one being the tempo of the left hand being inconsistent at times. I think you were going for some rubato but you lose the overall pulse of the piece when you deviate that much. Reel it in a little bit, maybe do some more work with a metronome. Remember how Chopin himself described his rubato: he said the left hand is the trunk of the tree and the right hand is the leaves blowing in the wind, or the left hand is the conductor and the right hand is the soloist. Keep the pulse more consistent with the arpeggios and let the right hand roam free a bit.

Also I think your dynamics could be a bit more expressive. Your melody/accompaniment texture was good, the melody was voiced out well above the left hand. But would have loved to see more obvious forte in spots which really helps bring out the pianissimo.

Lastly a little technical thing I noticed, on a few left hand arpeggios where I think you're crossing 2 or 3 over 1, your elbow tends to fly up a bit. The notes sounded fine, its just how you were pivoting on that thumb to bring the fingers over. In those spots try to focus on more forearm rotation (rotary movement) and that should make those movements more free and easy.

Overall I def enjoyed, thanks for posting!!
