Very well done! My biggest comment is on measure 4.
The run in the right hand seems kind of loud. I understand you may not be able to fix that, so if not, don't worry about it.
The melody notes need to stay loud and clear, but the run is a background thing. It should (usually) be much quieter than the rest.
The tremolo in the left hand seems overbearing.
I for one am not the hugest fan of left-hand tremolos, because they easily provide too much sound, and can drown out everything else.
That wasn't really the problem here though.
With that tremolo, I feel that the nature - the feel - of the piece was lost. I would recommend leaving the left hand there just like the other measures.
Another thing that kinda worries me is that those tremolos don't seem... playable. They're notated for 32nds, and that is blistering fast. I don't know if that's even physically possible.
For measure 4 at least, I would keep the chords like they were in the past measures. It keeps the feel of the whole piece; something you did extraordinarily well right from the beginning.
Beautiful use of the pedal in measures 7 and 8.
In measure 19, the melody has that awkward tie into triplets. I believe if you eliminated the tie, and made the triplets, G, F#, E (in descending order), that would be more normal and accurate.
I think the right hand overall could use some more articulation, such as staccatos and slurs. For example, a slur from the B to the F# on beat 3.5 in measure 1; and staccatos on the the last eighth note of measure 1, and the two eighths at the beginning of measure 2. Whatever is done must be repeated in the measures with the same theme.
Easily 90% of the time, it's the articulation that sets the difference between a good or bad performance; a computer playing the piece, or a real human.
The other thing that goes hand in hand with articulation is feeling. If you play with feeling, it's completely different than just playing the right notes. ... But now we're getting into musicianship. Nothing you need to worry about here.
This is otherwise a brilliant arrangement. I look forward to seeing more.
