It's very nice playing. I'm well familiar with this nocturne, having worked on it daily for a year or more. Just a couple things I'll point out. In the second section of the piece you really pick up the tempo for a moment, and it feels incongruent with what has come before. Then, after the trills and runs, you'll want to make the reprise of the theme stand out, as this is a denoument before it fades away. You handle the trickier areas rather adeptly.
It's a lovely piece, and lends itself to a rich interpretation.
