A few things I reflected over:
I've heard a few of your tracks, and it'd be nice to see you expand colour palette a bit - some soft woodwind harmonies could definitely have found their place in this track. Also, perhaps some more varied use of brass in general - piano brass harmonies can be very suspenseful.
The production of the track is splendid, no worries there. There were a few times when I'd wished the lead instrument was more humanized, but not often.
One thing I reacted to about your arrangements - there's some, but not very much contrary motion. Parallel motion and overall direction can work as a great build up device but contrary motion can give this very satisfying, solid feel. I don't know if it's something you keep in mind while writing, but if you don't, start to, it pays off!
One last thing, and it's a bit of a matter of taste - but to me the raised 7 - raised 6 movement at 0:39 really stuck out in an unsmooth way.
Okay, time for me to stop nagging about silly things and listen to it one more time!
