Jazz Brass Quintet?

I've always loved brass quintets (being a trumpet player myself), so I started arranging some jazz standards for brass quintet. Most of them were kind of bad, but this one I was really proud of - it's an arrangement of Thad Jones's "A Child Is Born". I used a little reharm in here too, but the end result I'm really proud of.

I like the idea of this. I also like the way you've arranged it, especially some of the reharm. Never been a great fan of Thad Jones, but here I'll make an exception. Would be nice if some of the other instruments (particularly trombone- but that's because I play trombone) got a share of the tune.
