The opening with the narration reminds me of Conan The Barbarian
Anyway, I don't generally do much in the way of criticism, but what the hell:
I would say that the tune doesn't feel "epic" to me. Your harmonic progression perpetually feels like it's building up to something, but when it loops back on itself like that, jumping back down to the tonic, it quickly kills the excitement. A progression like that is best used toward the end of a theme. Consider that around the 1:08 mark, you have this section where most of the other stuff drops out and you have that string ostinato; this would be an excellent place for measured tremolo. It also feels like this should be a section where we get a moment to breath and a sense of relief from all the action, but because the dynamics and orchestration are so consistent, it just doesn't deliver.
Another issue is a lack of movement and rhythm: a very common problem in modern orchestral music. You have a lot of sustained notes and basically your only sense of pulse comes from that ostinato and the drum hits. I would definitely use more articulations.
A big problem affecting the overall piece is a lack of variety and dynamics. The whole thing is hovering around roughly the same dynamics and is mostly the same ideas repeated throughout. Not something I associate with "epic". Most epic pieces of music start with a simple theme, orchestrated to sound tiny, and then re-introduces it later in a larger, louder orchestration. It sounds like you're trying too hard to make the whole thing feel "big", but in doing so, you have the opposite affect. Remember, without small there can be no big — and yes, that is what she said.
Anyway, here's an example of something that illustrates the dynamic and orchestration "build" with larger reprisals that I'm talking about.
