Works good as a loop!
but there was only one real gripe I could point out, the lack of reverb. when the strings come in at around :30, they die out way too quickly, giving the obvious sense that it is a synth sound. add more reverb (echo), and it could make this already spooky loop sound even more...spooky. :P

Didn't notice that about the strings, seems obvious now. Thanks.
It's a slower arrangment of graveyard groove.
