Children (Awake Remix) Almost there
The bass wobble needs to be much more prominent. Add some sort of compression in whatever program you are using. It should be the focal point of a dubstep song. Also, modulate some frequency shifts in the bassline. You can fade it in at a higher frequency, and then drop the frequency when you want it to fully hit. A dubstep bassline needs to sound thick and heavy, which sadly this doesn't.
Dude, do this, and this will be a perfect 10 out of 10 and a completely genre-bending dubstep song to boot.
