I really like this style of music, the song is very good, though I do have a few tips, I don't know if you already do this, but I advice putting small filters on everything in the song seperately, so that if a lead is mostly in high frequencies, filter it's low frequencies etc.
if you do that, I also advice you to download a free vst plugin called OTT from xfer, it's like... a multiband compressor, and it can make stuff sound really big if you turn down de dnwd knob, and to make it a little more balanced, you can turn down the depth knob as well.
I also advice you to use more reverb, like a lot more, but that's just what I think. still overall very cool dubstep song
