Great job! Though it's not quite an epic. He is right about the mid ranges, it does seem a bit cluttered, and maybe you could add a bassline to it to using a bassoon or string bass. Up the high range volume a tad to get that brilliance proxx mentioned. The main thing that's getting me though, can you record it at any higher of a quality? It just doesn't sound clear to me..I'm really picky about that lol. But you really did do a good job with this one.
One other little tip for when you're making this games music: don't forget about medieval percussion...timpani can have a huge impact. Later tonight (maybe tomorrow) I'll post a couple of example pieces for you for some ideas/inspiration.
Managed to find a good one you can get ideas from while I was typing this, its not amazing but I see plenty of possibilities with the instruments he uses and what you're trying to go for.

Anyways, there's my constructive criticism for the day.
