It does have an epic feel to it.
Personally, I like epic songs. However, I felt like it was missing something... perhaps a change in the background every once in a while or a sweet bassline, or a fight scene would make it a little better to put it over the top. But it does capture the empire feel, it kind of made me think of the American revolution, and the choice of lead instruments was good.
9/10, 4/5. I'm seeing potential in this song... good job!
