Umm, don't really know what to say :S
I don't know whether to call it a wonderfully made, suspensful ambient track or a discordant mess. Nah, It's wonderful don't worry :P
It starts off well, with an instant build-up to something. I can imagine this in some sort of Criminal Minds episode where the killer is entering the house and moving closer and closer to the victim, when at last he kills the victim.
Something which it also portrays is endlessness, like a sort of abyss, especially that growling sound at 01:22, that was quite a nice touch I must say :)
I really like the chords that hit at abou 01:59, They really sound cool.
For an ambient track, it gradually seems to get 'busier'. I know layering is essential in a genre like this but you can't overdo it.
Technical-wise, it's a pretty well mixed track - It's in that limbo between clean and atmospheric, above average mix over here, nice job.
What could use a little work though is the volume levels, some of them are out of whack, I'm listening to this on a modified system so I have problems on my end but I think it's the track itself that has a problem, certain sounds need leveling, rather than being layered on top of eachother.
I have to stop now because this soung is scaring the shit out of me :P
Nice job, 9/10 and 5/5
