Sorry, but this isn't too good at all. The bass drop is practically nonexistant, the wobble repetive and annoying and the drums don't support the track at all.
Here are some suggestions:
1. Start out with easy drumbeats, don't instantly try to make extraordinary ones (because you'll fail, as we can hear here). While the wobble is usually fast-paced, the drums are halftime in dubstep, meaning that you got a downbeat only on the 1. Keep that in mind.
2. Don't just let the wobble play all over the place, but come up with a concept phrase that you can vary - if you listen closely, alot of dubstep is like that.
3. For gods sake, fill that mix up. Dubstep shouldn't just be drums and a thin wobble. Get a better wobble sound (use Native Instruments MASSIVE, it's commonly known as the best bass plugin there is), some new drum samples (have two bassdrums - one deep one with alot of bass pressure and a higher, punchy one) and add some texture / ambience.
4. Vary the wobble not only by speed, but also by filter type, LFO waveform etc. Experiment and don't just follow the standarts.
