Very nice job here, but...
it's too repetitive! The beginning - it's marvelous! But then I feel something is missing and I know what is it. It's harmony - the same pattern but in many instrumentations - that's a plus, but still to little changes in harmony. Like other say - it's perfect for a fable game, but for a song you need to add more patterns. Overall GREAT JOB!! :D I wish you good luck in you career.
Cheers

P.S. For sure I will use it on RPG session with my friends ;)
