Escaping On Blues

I've made some revisions to this piece, it used to be called concert band, now it has a name lol. Thanks to @mysterious_hero2, with a great idea for a name this is now called, Escaping On Blues, again thank you, I might not have thought of a name for the piece. This piece uses the blues scale throughout the melodies and chords, I got the idea from recently being obsessed with "Blue Shades" by Frank Ticheli. Let me know what you think and what you think I could do to improve this piece. I hope you enjoy, and thank you for listening!
