I agree. It needs a lead synth to make it unique, although I do like how you modulated that high synth (not the wobble itself. it sounds like some sort of filter modulation). I don't listen to a whole lot of dubstep, so I don't really know if this is unique. Also, I agree that the snare is way to loud.
Try making the wobble rate on the bass the same as the kick when the kick goes to 16th notes (like around 1:28). I find it gives the track a cool pumping sound. Maybe add some hi hats to make it roll along, too. And as D&K said, find your own style. Experiment to find what fits.
But for your first dubstep track it sounds pretty good. Keep going!
