Overall, very nice stuff. Good harmonic language and changes. Nicely mixed as well. At first I was thrown off a bit because it wasn't huge and epic from the start but then it really grew on me. I do think there could be a slightly larger layer which isn't heard in your music just yet. But it was effective and interesting. You've definitely got talent! Keep it up!
Edit: One other critique is that you change textures/themes often. That's not a bad thing by itself but doing it too often can create a piece without identity. Epic Music #2 did a better job of keeping within a basic arena while the first track was more... scattered, in my opinion. Something to be wary of but overall, I really enjoyed both of your tracks.
