I loved the beginning, but then... that dubstep kicks in! Feels like the atmosphere is lost in the savored sawing of the track. I think chillstep might fit better overall with the vocal sample, and it does move in that direction at times but never fully as chill as I'd like it to.
The voice is a bit low sometimes, some words are easy to miss, like towards the end of the intro, but it phases in and out nicely. I like the shaky sound of that sample, but I just can't dig the vocal/audial combination too well. The closest to my liking that it gets is right at the start and at around the 3:30 phase. Keep at it!
