This track is amazing.
Some small things, first up:
- Beat 1.25 (the second note) of m5/41 should be E# instead of En.
- The second half of m6/42 should be written with naturals and sharps instead of flats and double flats because it's ascending chromatically.
- I would suggest adding double barlines at the beginning of m23 and m31.
- For patterns like LH beat 4 of m33-39, the two tied sixteenths should be written as an eighth instead.
And now bigger things:
- A lot of the time, you only have the RH playing notes, which really takes away a lot of the energy of this track because it makes the melody sound weak and overpowered by the LH chords. I would suggest adding either harmonies (improvise your own) or octaves in certain places to make the RH line stronger, particularly m9-10, m15-20, m34-40, and m43-47. I would suggesting add harmonies/chords in m9-10, octaves to m15-16/19-20, harmonies to m17-18, octaves (maybe with some chord harmonies too) in m33-40, and so on.
- Those consecutive 16th notes in m15-20 LH are nowhere near playable. Can you try changing that part to something else?
- I like the chords in m21-30 LH, but without the driving rhythmicity you had in the LH before m21, m21-30 (which should be the most climactic part of the track) really loses a lot of its impact. Try finding a way to merge a similar rhythmic LH pattern with the chords you have in there now.
- In m45-48 LH, I would just suggest using something similar to what you have on the first page instead of what you have now. To play this 16th-note line while sustaining the whole note, you'd have to pedal (which would sound terrible for the whole 16th-note line), and the 16th-note line just isn't as harmonically or rhythmically important as the chords you had previously.
