I like what you've done here. You've responded to the awkward ensemble constraints with music that gives the impression of being slightly uncomfortable with itself, but I like that!

Score-wise, I believe it's standard practice to display staves for all instruments on the opening system. Also, have a look through and fix the various colliding elements (nothing is colliding in a big way, thankfully). In addition to that, you appear to have mixed up the fonts used for dynamics - compared bars 38 and 39. Then go through and find the spots where the rests have gone wrong slightly, e.g. sax in bar 46.

Musically, there isn't really much to give feedback on, as it works quite well overall. All I would suggest if pressed for criticism is to consider using a few more punchy cluster chords to break up the flow now and then (in the same vein as the last quaver of bar 39).

Thanks for sharing!
