The synth stabs were pretty well done. I enjoyed them well! The actual dubstep needed much more variety on the drums. Muuuuuuch more. If you want an old school dubstep sound, you want more industrial sound caked with carefully arranged reverb, but if you're going for something more modern, you need to hit hard. The bass was done well, but maybe some resampling could keep it interesting. At 2:40ish, it get's rather good. I like it very much. Needs more sub bass, for sure. Especially layered with the kick. Very well done, I liked the composition, loved the samples, and generally very excellent. 8.9/10
