Dark! Cinematic! Chase!
I really like the low percussion right in the beginning. It's sort of like a mix between boot stomps, war drums, and muted gunfire in the distance.
The faster accented notes in the strings sound like you painted them into your DAW. When it comes to orchestral work, I'd typically recommend playing things in live so you get more variation in timing/velocity which will give you a more realistic performance. If your piano skills are anything like mine (not great) you can always go back and push notes around or semi-quantize to get things more on time.
The EQ on the tutti strings sounds a little bright when compared to everything else as well. I'd consider rolling off some of the extreme highs just a touch to help blend them into the texture a bit more and soften the attacks a bit. Realistically, an ensemble this big would have to be housed in a very large room to record everything. As such, some of the higher frequencies of the strings would get sucked up in the space while traveling to the mics.
0:43 - The arpeggios in the cellos sound a bit unrealistic. If I were actually playing this section as an instrumentalist, I'd accent the first beat of each of the arpeggios (and maybe lightly accent the high notes a little), and the subsequent notes would be much less so. If you play this on a keyboard, the effect would be much the same.
That solo viola(violin?) sounds great!
Those war horns and crying are a powerful moment. The juxtoposition is really evocative and pushes some vivid imagery.
Compositionally, I think I wanted more out of the development. It's a little on the short side. You introduce some really great musical themes, and then the piece ends, but the epic beginning made me feel like this should have been longer if it's a standalone piece. If it's programmatic (it's telling a specific storyline) or it's envisioned to be the score for a film, I would make sure to mention that.
