Eerie vibe
Overall, this definitely got the 'eerie' sound right, thanks to the bg noises and key choice. A few things niggled at me though - in the wrong way.
The 2nd phrase - starting at 0:13 - seems to be played slower than the 1st and generally there seemed a slight lack of rhythmical unity here.
Maybe that adds to the eerie atmosphere though.
The notes starting at 1:27 seem like they're in a major key and kinda uplifting. Though you throw in a minor chord here and there, the song definitely ends on a more positive note than it began.
Throughout the song, though I could hear lots going on in the background, it seemed kinda cluttered and I could only really make out the main melody, which was kinda simplistic for the first minute or so. Maybe throw in countermelodies, confuse us as to which one - if any - are the lead and disorientate us. Maybe check out Tim Follin's work for Equinox (SNES) - it's very different, but has a couple of similar aspects.
I liked the background clutter and the pacing itself.
