it doesn't sound very good, you need a basic melody (for example maybe a trance beat or some piano keys) and a drop. You seem to only have a build up which is not very good, and the speed of the 'wobbles' seem as if they are random and not controlled. Try to use programs such as FM8 (which is basically like sytrus but just changed a bit) Harmor is also a very neat program, but is very underused and under rated, and also try adding vocals in the song (not during the start I mean in the actual song) and you also need to balance your sounds, I can barely hear your kicks and snares infact I don't even know if you used any hi hats because the sound was soo loud compared to the beat, and your main beat (kick+snare) seems off, it sounds like that you've only used two different versions. Try to play around and make around 4-6 different beats. Use different kicks and snares (I recommend downloading Deadmau5s sound pack) and make your snares more dubstepy. Artists typically don't rely on massive as you're doing in your track because their is soo little you can do with it compared to FM8 or Harmor.
Heres a sample of what I've created using FM8 and Deadmau5's sound pack on fruity loops

Depending on what your going for I'd recommend to listen to Borgore or Skrillex or Tomba if you want the heavy type of dubstep. If your going for something along the liquid dubstep genre then Listen to Blackmill which is much more calmer and relaxing.
