An excellent arrangement, with great composition. The point of contention, for me however, is the choir. It sounds too...synthetic in direct comparison to the grand majority of organic elements. It stands out quite a bit, though I wouldn't necessarily say it ruins the piece, just that it's a sour note in what is otherwise a great listen.
I feel the woodwinds could have been a bit more on key and in tune. It often felt like they were off during their solos. However the brass and percussion killed it. It certainly made up for the inadequacies of the saxophone parts.
