Spaceport AlphaSorry that this one's been waiting a while. This a pretty cool piece.
Left hand notes:
-Every time you have the pattern on beat 4 of bar 1 (i.e. lots of places) I think that should be two semiquavers at the end. It'd certainly be more consistent with all of the other times that rhythm comes up for different pitches.
-Bar 10 beat 4.5 should be another C.
-Bar 11/13 beat 4.5 I hear F# -> B rather than E E.
-Bar 15/17 beat 2.5 should be an F#. Nice descending tritone there.
Right hand notes:
-Bar 7/11/others, the little interjection on beat 2.5 should be D B not B G.
-Bar 10 missing harmony:
-Bar 18 beat 2 should be two semiquavers rather than a quaver.
-Bar 35/37 the Ebs should be D#s.
General arrangement points:
-I'd recommend trying to get some of the harmony into bars 11-14. The harmony that is outlined there is B -> Em -> B -> Em -> G (by the harp thing).
-Generally speaking, I think the left hand should be lower. Currently it really lacks the power and the drive of the original. Honestly I think you could just put the whole thing down the octave, you wouldn't even really need an 8va anywhere.
-I know I suggested adding in harmony for bar 10, but I think bar 34 has too much. Those chords are by far the most awkward thing to play in this arrangement and I don't think the difficulty spike really benefits the sheet.
-21-28 might be a good place for an 8va.
-Make sure the slurs in 35-38 end on the ends of the ties (i.e. a note later than currently). Also, I think the slurs could made a little more consistent by slurring it like this:
-I'm not sure about the staccatos in 21-28, they don't sound particularly needed there.
-On the other hand, the RH dyads in bars 3-6/19-20 feel like they could really do with some staccatos.
-I'd suggest slurring the first and third quaver in beats 3-4 of bar 8.
-A general comment: there's a bunch of places where the RH swaps to and fro between two different voices. It might be helpful to break the beams in these situations to make it clear that the voice is changing, or alternatively use phrase marks to help distinguish them better (although both of these options have their downsides... See what you think.)
