Slender man approves! (Faceless creepy bastard...)
This song sends chills down my spine! I only have three gripes with this:
1. The random flute-ish noise around 0:27 sort of spoils the moodiness.
2. The ends of the loops don't neccessarily match.
3. Lack of a bit of substance in industrial instruments (Although this doesn't present much of a problem, as it is reminescent of the Silent Hill games.)
You are on the right track with this! Just a little more work and this can work as Slender Man's haunting theme!
(P.S. I'm not trying to flame you. I'm just trying to deliver some constructive criticism.)
