This could be a Dreamworks score - beautifully tense, dramatic and well written / arranged and played. This is master-craft musical scoring at its very best and you should be very proud of the vision and narrative that this music conjures for the listener.
What movie is this going to be the sound track to? Have you sent this off for publication? You should. Nice horn writing, nice harmonies, timps were effective, nice swishy (whatever it was) background, too. Sensible ABA form.
