Wonderful. o:
The only thing I might have is maybe you don't want as much attention drawn to the risers (especially that one at 0:44) , I believe that they add far more if they are in the background, instead of the frontlines, hitting hard, if that makes sense.
Besides that *minor detail*, I really like it, like alotttt! That trumpet/trombone is stunning, and they way you bring it all together is wow.
Overall wonderful track! š
