Alright.

The individual melodies sound great and all, but the way you combined them could've been much better.

-Snare drum synth sounds like crap, no offense.
-Everything sounds too generic. I was hoping for something really epic considering the name of the track, so maybe try changing up the way the instruments sound a little bit.
-The panning of all the instruments is out of whack. I don't like have one instrument on one side and one on another, but that's just my opinion.
-The low-key end of the piano solo kind seems out of place and doesn't link all the epic parts together very well. And it sounds like a children's music part.
-The song is really low quality, the louder parts of the song are buzzing my speakers. Maybe try reducing the song's volume when you export it?

Other than that, it's not that bad at all. But without a doubt, the melodies are pretty fantastic. It's just about how you're gonna link them together now. Hope my review helped a bit, good job man.
