I like the synths in this

But I reckon to make it really powerful dubstep, you'd need some intense punchy drum samples. I'd recommend the vengeance drum sample packs. This is a fucking sweet song though, nice work.

Okay, I thought, great intro, sweet piano melodies, punchy drum sounds, nice leads, clear mixing.

The main thing I think you should work on more for this song is that wobble bass. I'd personally say leave out the automation/lfo/whatever is is controlling the filter, and just leave the bass as a dirty "reese" sound. Then, to keep it interesting I'd say put over some really haunting reverbed vocal samples in the odd place. You don't need a wobble bass for it to be dubstep, and I love the parts without the wobble, but in my opinion that wobble is a bit too "cheesy dubstep" sound.

That's all just my opinion though, and it was worth a download. Stay proud of it- the people you've showed are right to love it, I'm just giving a suggestion for what to do next.
