I love it. It sounds like a song I would probably hear the game "Dungeon Explorer" or "Ys Book I & II" in which had fantastic music. I just see the epic quest of valiant heroes through a perilous dungeon or field of common that which by night terror strides through it.
Overall I loved the song, the beginning kind of worried me a little bit, but it just ending up being very smooth and quaint while being a strong song as well.
I can definetly see what you see---both the strange start of the music itself, and the epic feel of adventure throughout.
