This needs chords, and watch the clipping. In other words, you need to go over all the mixing. Also, I'd like it if you changed up the chord progressions and styles. Add some M9 and M11 chords just to spice it up a bit. The lead is decent. No offense, but that growl sounds kinda outdated, especially in a genre (dubstep) that seems to be dying. For glitch hop, it could do to be a tad faster.
