Overall nice, still needs some work though.
The wobble was pretty nice here. I also liked the synths at 0:49.
There is a problem though. It really sounds high pitched. For example, the kick is fairly short and hollow, while it would be better to give it a more punchy sound, to get more of a dubstep feel. The high percussion, too sounds a bit high pitched. Perhaps a slight filter or a simple hihat pattern to replace it would please the listener a lot more. I would recommend a nice punchy kick and a good firm snare (not too loud), to make the song stronger in structure.
I'm not sure if you tried to make it dubstep, but for dubstep it needs to be around 140bpm. After some listening I think yours is about 120. If the structure of the wobbles will be affected by, then I would just leave it at this tempo.
So I would give the kick a good punchy sound, replace the clap with a firm snare (or clap) and filter the high percussion (or replace it with a good hihat pattern).
It would perhaps be nice to put in a main melody, to give it more of a song feeling, but that's up to you, it's not necessairy.
The wobbles and synths/pads are nice, it just could use some work.
Keep it up! :D
