Real simple, not much goin' on
I really don't like giving bad reviews, but I will be as constructive as I can:
There were maybe 5 channels in this whole track, which is pretty plain-jane. Especially for a track that seemed to start off somewhere between trip hop and d&b, I would have expected more substance. It needed a few different themes (like more than 1 simple melody) and a few different beats.
You should consider using a pad (as in background chords to give it some substance), particularly during your breaks. At 0:51 there's basically nothing playing but the beat. Which, if you had a complicated and intricate rhythm section would have been a nice touch, but you can't run the same hip hop beat structure ALL THE WAY through a song and use it for a break beat. It's like shoving it in the listener's face that there's nothing happening with the beat when you let him hear it alone like that.
There was also no Bass riff whatsoever, just a square wave in the background (which doesn't count as a pad when it's actually playing some kind of melody) that didn't change throughout the entire track.
Given the lack of variety in this track, it could have been shortened to a 15 second loop and it wouldn't have lost much of its substance.
