I found this be wonderfully pretty - I love this kind of sonority. Yet I feel you don't adapt completely well to the large scale of the piece. I was really interested at the beginning and loved your sonority, but it started to drag and the harmony felt more and more lacking as I didn't feel enough variety. But you *did* have variety eventually, and wonderful variety (the passage after bar 39 was lovely) it's just that I feel this is a piano miniature that was slightly inflated. Personally if I heard this in a concert hall I wouldn't be bored, because I find this very beautiful - but I *would* be aching for something a bit more dynamic after a while.
Other things I loved were that jazzy touch in bar 57, and the phrase after bar 64 that brought a smile to my face. Personally I found the ending to be unfulfilling for the same reasons chodelkovzart liked it

I was aching for something a bit more cadencial and conclusive, but that's a completely subjective thing.
Congrats on a lovely piece.
