I don't really have much to say here, looks really good
- The fermatas in m6 should be lined up - so you should write the RH as two tied dotted quarters, the second one having a fermata.
- The rolled chord marking in m10 would look better if it was a tiny bit closer to the note rather than the barline, and the one in m32 should have some more space around it.
- If you have multiple tempo/style directions on the same system, it would be nice if they were lined up, provided there's space (like in m2-4 and m13-14).
- I'd be fine writing some of those tied LH rhythms as dotted 8th notes (I'm referring to spots like m18-20), since you use a similar beaming pattern in places like m11 and 15-17. Maybe it's just me but I don't really like the look of having ties in beamed notes, but it's up to you.
- The small fermata in m46 looks like it should be moved just a hair to the right so it's centered over the notehead.
