Fantastic beautiful great, I always have a soft spot for Chopin's Nocturnes. The LH thumb isn't distasteful in my opinion and essential, those long bass notes I always feel should be drawn through. Some quick patterns in the RH need to become slightly lighter (although I can hear the RH has had a lot of sensitivity practice). That is the biggest challenge I feel for you here the RH lightness, the LH is fine and dandy. I really like how your melody fits together with your LH its not always together and boring, there is options you are taking which makes the playing sound "nicer" in my opinion. I find people muck around with the LH too much, where it is the LH that should be quite strict and the RH with the rubato.
