This is so creepy! o.o I like it!

I feel like this has devastating potential to be an epic, doesn't seem to fit cinematic that much. Like, the from 00:00 - 00:11 could be looping throughout the entire song, with other, perhaps melancholy sounds playing. And if it was going to be sad it should stay at a slow tempo.

Amazing.

I don't know what you could've improved on as I truly feels this encapsulates the feeling of being in a dungeon, lost with no bearings, unaware of what terrors may lurk behind every corner.
