Far too shallow
Sounds more like a WIP IMO.
The track mainly consists of one synth and the drums at any one point. Sure enough the synths change around, but I don't see this as a proper dubstep song. It's very simple. I like the rhythmics you have in the intro, but the intro is waaay too long and dragged out.
I can't really hear the dubstep in this either, the synths not very wobbly and very few parts of the track remind me of dubstep whatsoever. Ending is also dragged out quite a bit.
In general this needs to be fleshed out, as it is now it's barely even a WIP.
