Hey man,

Your track starts really ominously, the twelve strings sounds cool, the string synths sound quite 80s. The track grows slowly but aggressively, keeps you on edge. The atmosphere builds and it sounds very full. For a track this length, a listener might expect a melody or something by about half way but it works quite well as is. The mix isnt bad and the track has a really clear intention about it.
The track is cool, I like the change up at around 3:50, really makes me wanna listen more.
I would say for improvement it would be cool if it had a bit more variation in it to keep me interested, but otherwise cool track dude.
