Right on key; but too orchestral.
While the sound is amazing, it seemed more calm, while a battle is more meant to be "intense," per say. Not to mention that it sounds too orchestral. Other than that, you did very great here.
My Ruling
-----------------
9/10
4/5

Still did good. Just gotta make it less calm, and make it less orchestral (but not too much, or you'll take away from the epicness of the theme in itself). Should you make a 3.0, I hope my suggestions help to make it better. :)
