I'm not super at this whole feedback thing so I doubt anything I say will be too helpful, but there's no harm in trying. I'll just say whatever comes to mind as I'm listening.
Interesting, very different from the source material's start. Much less haunting and more ambient I'd say. I like the gradual transition into the main theme as it gets creepier and creepier, nice touch. Very "alien" sounding by the end, not sure any other way to describe it but it's pretty cool. Can't think of anything particular negative to say, but I am pretty easily pleased.
