Very nice but room for improvement, first of it starts and stopps too fast which can sometimes add effect, also it could be longer, it's not really dubstep, more chipstep-Like, i still enjoy how it was composed, overall it's good, just minor tweaks.
(Also i diddnt notice you had lots of thing posted before i pm'ed you XD AND!! Dont be afraid to show emotion on ng, it's proffesional like but you can still have a soul XD)

mmm ._., well before the grainy bit kicked in I was in tune with the boss dialog part, I totally imagined that as a megaman battle dialogue, the grainy part that comes in at 43 sec, I feel that it should be moar steady...like..beat wise, and for personal taste, some of the notes not sharp or as detuned.

I really enjoy this one. I think you accomplished the imagery you were aiming for. I particularly like the beginning; I think the soft, warm string pad really compliments the harder, busier "reverse" feel in the lead. From seeing your other work, I personally feel like putting in some extra time on this song - adding a bit more to the end and making it loop (due to your proficiency in looping) would have been worth it. I think you had enough material to be interesting on a second pass at least.

Love how trippy it sounds. At first I thought it kinda got heavy around the end but it really helps push the creep factor you have going, so it's a really nice use of distortion. I can see this being played before a final boss or just a creepy character. Awesome track.
