Thanks Jonny! It is a great piece, it's been a fun project. The second movement is also great - this was pretty fun (not me):

Maybe I'll get around to organizing my chart...I really just simply looked at how the voices stacked up and put chord symbols on them (mostly it's just triads over bass notes and some seventh/ninth chords), and for improvisation often took sections of the melody as "pitch collections" and practiced inversions of the patterns within the melody as motific material. (there's a part that's mostly just G9 to Bb9 back and forth, and over that I played a little more vertically than horizontally)
In terms of pitch selection I usually tried to stay pretty strict within certain sets...gotta run for now, maybe later I will post about the patterns I practiced for improvisation. I did this for an audition yesterday so I've been working pretty hard on it.
Key thing with this was the intervals, melodically. There's a certain blend of fourths, fifths, thirds, and step-wise motion that's kind of delicate. I don't think I necessarily achieved that (it was the goal), but the idea is that too much step-wise motion and you're running up and down scales, too many fourths and fifths and it can sound like something from a modern jazz exercise book.
More later, thanks for watching!
