WOW!

I could see this starring in a cut scene of a flash game where the character fights a boss or something, then goes on to discover something amazing through much traveling hardship.

GREAT

This song has a relaxed then anticipated then pump up feel to it. It's a combined cycle of these emotions. Very good!

AMAZING

So many details put together for a unified-sounding aura. Simply amazing! You should make tutorials on how to create songs like this one!
