Hello deandeblock!
Good to see you are still working on this piece. It's a working progress so no criticisms, just things I can suggest working on.
1st, tempo, not necessarily just a tad faster, but maybe less robotic and more free, that is to say as the melody dictates it.
For example around 22seconds up to 44 seconds is a place where you can add some dynamic that build up and slightly increase the tempo to then resolve and go back to the smooth pace.
Rather than trying to make that bit particularly loud, concentrate on making the rest quieter, left hand has already been mentioned.
For the chords at 44 seconds, trying putting more emphasis on the melody note (top) something that my teacher commented on my own playing when i performed this for him. Try and feel the concentration of your hand leaning torwards that top note and the thumb just providing a very quiet echo of the lower note.
For the little tricky bits (for example 1min 10?)isolate them and just take them out the piece, run through them slowly 20-40 times per practice until you really know the notes then slowly work on tempo and bringing them back into the piece, do so by adding a bar or so of the piece at before the tricky parts and after so you can feel it back in the piece.
The chords in the middle were good, I heard the top melody note quite nicely and so there just work on making the start of it quieter so there can be more variation in dynamics.
When two sections repeat like that the suggestion would be to play one slightly different to the other, so i'd play the first run through quieter and the second a little louder especially as we're coming up to a sort of coda.
Ornament around 2 minutes was good. as well as 2.30.
2min 40 again i'd say a slight variation in tempo as the stress builds a little.
3 min 10 the little flicks are deceptively hard to have PP if i remember my score recommended 2/1/4/3/2 or something like that which allowed you to get good control.
Nothing really to complain about here, as you said it's a work in progress, and a couple weeks I imagine you will have this at a good place.
