Pretty good.

—warning nitpicking ahead—

It needs to be more… um… scarier.
Low pass filter the kick?
It's a little off time (I know, i know), so you might want to get a silent metronome and/or drum machine?
It's supposed to be dark, so maybe add some slight distortion on the kick or crusher? Maybe? No?
Your percs choice was a bit wonky for a horror song? Needs, um, less cowbell?

Supermarket would be better if the dark part/transition to the dark part was a little more distorted or crushed? Love the sounds there.

omg illusio best. You might want to consider a ping-pong delay on some of the background percussion - it's where you make the sound seem like it's bouncing back and forth. I think I can hear a little reverb nasties on the pads - filter those?

You probably want to remove the kick entirley from evacuate, as it seems a little cheesy or something. And the ending is boring as ever.
