The intro chords were interesting to listen to for a while, but it got boring quickly. I recommend expanding on the theme or introducing different voices earlier in the piece. Don't get me wrong, the theme is pleasant but it get's boring quickly after being repeated. However! I do like what you did with the trumpet solo at 1:50-ish, it really added some spice. All in all, it's a good piece but it needs to be developed more to be truly appreciated.
PS. I know it's labelled as epic, but you can add some flutes to it too! Some soaring high notes would really get the adrenaline pumping!
