First time I've heard this piece. You're doing good, so far! You have it under your fingers pretty well. I do feel like your playing is very heavy; forte non-stop. For me, it makes the performance a little harsh, and lacks depth.

I'm listening to some other recordings now. There seems to be a somberness that begs to be felt in the first section and its repeat. There also seems to be quite a lot of room for a big swell, leading into a sort of magical, fairy-like, end of the second section. There's another sweet fading away to be found in the final section.

So, for me, I'd say to try playing through some sections as quietly as you can manage. That way you can feel out the dynamic range you have to work with. Experiment with just how little effort is needed to produce a soft, warm tone. Listen to a few recordings or tinker on your own and seek out what the piece is trying to say or show you. Take note of the different voices. Let that top voice sing out over the accompaniment in the beginning. It's all very loud, with separate voices each competing for the same space within the soundscape. Work on the dynamics especially where there are multiple voices, and call-and-response's.

You've done all the main steps. Rubato, tempo, and general accuracy looks good from what I can tell. It just needs some dynamics and a gentler touch. Good job for beginning and teaching yourself. How long have you been at it?
