I'll be writing this review as I hear your song.
00:00, great so far, very much promise.
The powerful synth I feel drowned out the bass drum, which I have a personally feeling about. I would sidechain that saw pad to the bass drum dude. and equalize it very carefully.
Follow that there is an acid synth with a trancy downtempo kinda rythm.
Some hits, and what's this! A crushed bass... I like (:

Slow hits... What is this leading up to?... WHAT
That's the end?

I feel this song would fit better in the ambient category myself. What did you use to make this? I didn't put the dubstep lable on it, but as a song I must say it was well composed. You chose a good set of synths man and the potential was there for a crazy drop but then it ended. I liked it though man so I'ma give you a 4... but vote you a 5 because it's pretty decent and I don't feel it deserves the rating it has now.

Nice
