I make orchestral music nearly all of the time, and this is really nice, especially for the first orchestral piece you released! This is very close to the "trailer music" vibe, I'd say. Nice chords and the instrumentation is pretty good. I'm not sure what samples or sounds you use for stuff like this, and while they don't sound bad, I think the overall sound could be better (no big deal though). The mixing is really good, and I'd say it makes up for the sample quality. I think you were going for a "trailer music" sound, so you'd probably need some French horns to make stuff even better!
I make trailer music a lot nowadays, so feel free to check out some of my music if you want!
