Nice composition, from the opening flute and harp, then the build into the horns and the cellos, then at 1:32 the drums kick in, I'm thinking...wait, the arpeggiator...nice...the strings at 3:00 are awesome. I think you could easily continue this piece for another 2 minutes without it becoming stale. I would revisit some of the opening parts and maybe blend them with some of the latter parts.
Epic music in the sense that Hollywood could easily use this in a movie. The picture of the mountain lends itself to imagining a song of adventure and conquest, or renewal.
Production sounds good to me on my headphones
