It really is kind of hard to classify this mix, to be honest. Not that it's a bad thing, in fact, the fact it tends to just pick up more and more through the song makes it fresh to the ear. The end of the song gets to be a little tid bit much for my ears, but that's just me. Great job!
Classic and creepy
I really enjoyed listening to this as it reminded me of going through the original Doom. It would be a perfect 10, but if the place you are referring to is a HANGAR, then that is what needs editing. If this was intentional, well, all right then.
