Well, it's an interesting piece, although I wished the whole ensemble being a little more dynamic in terms of audio compression and left some breathing space between each instrument because at the current state of things it sounds like a big cluster of sounds alternating with more other clusters.
It would probably also help if you gave your orchestra a more natural ambiance, like a concert hall or an auditorium, and you modulated your instruments with a bit more of vibrato and not just sustain notes that kinda fall flat after a little while.
As a final advice, you could try to humanize your instruments by playing with tempo automations and performing some slight changes in each note velocity and placement so that it gives your sound a less stiff, mechanized output. Overall, I enjoyed the structure and progression and it does give a battle-like atmosphere.
