Well done.....you've got the notes, and the tempo and rhythm are good. Now you can try to add some other things....
Ideally it should be much gentler and more subtle. The main thing is to play lighter, mainly in the right hand. (You have the L.H. nicely subdued most of the time, and that's great.) About the R.H.: Maybe try to think of how you would sing
it. There are certain notes that would be stronger than others, notes that you sort of "go towards." Notice what those notes are; don't "force" yourself to make there be notes like that, just NOTICE which notes those are.
And just "go toward" those notes, and subdue everything else, sort of "dying away" from them after you leave them. When this is done terrifically, it gives not just a singing effect, but "sighing" -- and then you're practically being Chopin himself.
It's not easy; it's very hard. But it would be good to try to do it at least to some extent, and without being mechanical about it or doing it exactly the same way everywhere. It's hard.
BTW: The middle section doesn't need the suggestions as much as the rest -- hardly at all, really -- because of the type of thing that it is.
