Very nice indeed. I enjoyed listening to it very much. I played it a little differently and I have a few suggestions as alternatives you might want to consider (or not;))
Rubato- At times I feel there's a little bit too much. For example in M10-11 I feel the phrase really need to go on to M11 and a little rubato can be taken at the very end of the phrase. The reason I say this is because this is the first time the listener gets to hear this phrase and I want them to hear it "as written" . When the phrase comes along again, I can do more with it.
Voicing- have you thought about which of the 2 RH notes you want to voice in M13-20?
M21- I wonder why you held back on the accents and the fermata note on the appasionato. Try it, you might like the passion.

It also provides a contrast to the a tempo p dolce following.
M31-32 and M33-34 again, I feel the phrase should go across the bar line. If you must take some time to get to the first notes of the next measure, make sure the listener don't feel the phrase is broken.
I loved your languendo section. I also wondered why you chose to slow down in the accelerando section. Try accelerating, you might like the excitement.
In the section Un poco piu mosso- I like the LH melody. If you can bring the same type of phrasing from the beginning of the piece to this section, it'll be great.
I loved your RH basso marcato...very nice indeed.
Very last line- very nice tone control. Question: have you tried counting out your rit. in the last 3 measures? As a listener, I am constantly counting with the music so I am doing the rit. in my mind as I listen. It might be easier to prep. the listener for those last notes if the performer also count out the rit..
Great job! I don't think I can play this piece now after leaving it behind for 15 years. I envy your great technique.
