Personally, i prefer to be more drum biased in my dubstep.

But this is pretty ok(acceptable not mediocre).

You could turn down the hi's on the cymbals to give more breathing room to the synths.

You could drop the synths down just a little bit to make the kick and snare punch through.

It seems like you're pushing the mix a little to much, if you do like tone it down a little bit, you can go back later and raise the overall volume, and it will sound SICK.

But this is pretty good.

NOTE: i turned the volume up, and the top end is just a little to much. kinda harsh.

It might sound better if you turn down a good bit of the hi end. If you make it a little warmer it would be good. The second part is better than the first after the "YOU FUCKING BITCH" part.

Thanks for the comment Marrow Machines.

The top end definitely needs a lot of work (there are problems with competing synths/hi-end hits that certainly need addressing, especially in the first part of this clip). I admittedly haven't spent a whole lot of time yet adjusting the mix since I'm still trying to get the general ideas and rhythms down first, but I'll go back and clean it up quite a bit to make it less grating on the ears.

I have some requisite, albeit limited, side-chain compression on the synths for the kick to come through, but I'll also go back and play around with that quite a bit more.

don't mess with your compression, it's the eqing and volume balance that's the problem.
