doesn't sound like dubstep to me at all and that beggining raped my ears try a lil less voume a bit faster polish it up
There is no melody, nor is there any contrast. The hit sound is bit crush galore and doesn't sound nice at all. Work on the sounds and changing the pace of the song. It shouldn't just be hard the entire time, a listener needs some time to relax. Listen to some popular electronic music that you like, and think about the dynamics of the song, it will help you structure you song better.
I'm gonna have that in mind when I continue working on it.
