-Throughout m1-21, any single-note C's in the L.H. like the first 3 notes in m1 should have their stems flipped.
-m1 and 5: I hear something like a Bb in the L.H. on beat 4, though it has a different sound than the sound of the actual bass.
-m1, 3, 5 and 7: I don't specifically hear the C in the R.H. on beat 2, though I'm guessing you put it in to imitate something in the total sound?
-m9 and 17: I hear Eb's instead of C's on beat 2 and 4, though weirdly enough only in these 2 measures
-m11 and 19: You can write the Gb in the R.H. on beat 3 as F# too, since it's going towards the G.
-m12 and 20: I hear this in the R.H.:

-m23: The F-Gb-F in beat 3 should be an 8th triplet
-m24: I hear something else here:

-m25-40: You left out quite a lot of grace notes here, was that intentional? All grace notes here (and in the next section) should be a semitone below the note it's going to (so C# to D, F# to G, etc)
-m25 and 33: The Bn's in the L.H. should be Bb's
-m38: Maybe you could add a courtesy accidental on the Ab in the L.H. on beat 4.5, since the chord here is F major (or F7) and the player might expect this to be an An too.
-m41-53: Was there a specific reason you decided to put a few bass notes here in its original octave? It's not unplayable, but it might be easier and sound a bit more coherent to have these up an octave too (including m47-48)
-m54: The R.H. F on beat 1.5 should be on beat 2 instead.
-m55: Maybe you could add a G in the R.H. chords too? It's just a very nit-picky detail, but currently it could sound like the Eb is resolving up to the G instead of down to the D: adding the G in m55 creates a separate stationary voice while the Eb could disappear to the D.
