Keep it up!
Though I know this is unfinished, I feel like there's something missing.. I can't think of anything right now, but if I do, I'll get back to you.
I can see jfig111's point of not liking the parts where is quiets down and bursts back up, but I think that it works well in making the louder parts sound more epic.
Also, the quiet part from 00:30 - 00:45 seemed a little too quiet for me. Definitely liked the flute in that part though, added a nice touch. The ending is nice, too.
Anyway, keep up the great work!
