I like the synths you used, and the melody.
But the drums aren't proper dubstep attire if you know what I mean. d:
That kick needs to be heavier, and punchy.
Instead of using actual drums use high processed snares and thick claps.
It seems all too random right now, work on your organization more.
though I rate this a 3 out of 5 I'll rate it an actual 5 anyways. (:
