Sound: There are mixing issues abound here, along with quite few things you can do to expand your sound and make it sound more epic.

Composition: The composition style is pretty straightforward, yet that also makes it slightly repetitive. Percussion needs major work as right now it's pretty flat and sounds like a machine drumming and not... live. The build to the end is weak unfortunately and needs work.

Fit to Art: The track fits decently well, although I think it lacks a general battle drive to it. Then again, the art doesn't depict the battle, so it's alright.

Originality: Nothing new here.

Nice composition Mawnz! The piano is a little bit repetitive but not annoyingly repetitive. I like the melody, good work!

Well orchestrated, nicely done! I really did enjoy this! A couple improvements I could suggest though:

-You need contrast in the volume. Your instruments are going at a very steady volume, and so the punch you composed isn't getting played! Time to fiddle with the levels!
-The piano, while lovely, is a bit repetitive. See if you can't get a bit more out of it by making the arpeggios have a couple 'filler' 16th notes. You're in a slow 6/8 or a fast 3/4 timing, so you can mix it up a little by having the 4th arpeggio played in double-time. It would give the piano just a little more complexity.
-Finally, keep putting stuff like this out! It was awesome!
