An Uptempo Jazz head

I composed a head and made a basic arrangement for the first play-through of the head. Here I did put in some written parts for piano and bass, though that was primarily so that I could hear what the trumpet and saxes were doing in something resembling the context in which it would be played. I'm mainly wondering how difficult this is for the saxes (are all those off-beat, short notes doable) and whether this is doable for a high school jazz ensemble. Additionally, I was wondering what you think of my harmonization and the melody and what others might have done differently.

I have three attachments. #104.pdf is the chart, #104.mp3 is the audio with the rhythm section, and #104_2.mp3 is the audio without the rhythm section.

It sounds nice.

The chords are confusing because they appear in every instrument according to transpositions.

What's stranger about it is that they're not chordal instruments, so unless they're improvising, it's not going to be very useful.
