This song....confuses me. I enjoyed it very much, but the feeling of it changes a lot for a minute and a half. It also sounded very much like game music to me.
I heard the introduction as an end screen for a Zelda-esque game ( I was actually picturing the game over screen from Ocarina of Time as I listened xD)
The middle (starting at approximately :34) reminded me very much of a backing track for a tense dialogue moment, perhaps where the characters are meeting the main antagonist for the first time, or have just lost a friend. Something like that.
Finally the end (beginning at around 1:12) felt almost like a bluesy, dingy city type song. With a bit more speed and some stand-up bass you could get a whole other song out of the last thirty seconds of this one.
As I said though, I liked it very much. My only real complaint is that it feels like you have the makings of an eight minute song (as far as mood and tone goes) crammed into a minute and a half.
Well done. =]
