Decenté

^ i dunno what that even means xD
Anyways, all you do need is massive man, trust me, most tutorials are pretty horrible, but DotEXE has some good ones, go check him out on the utubes. All it takes is practice man, every artist will tell you that, just lots and lots and lots of practice, took me a year to finally know how to work each knob and everything. My friends been producing for 4 years and he still doesnt know how to work each knob :P

K here are some pointers.

1. Take the limiter off every time you open fl, it just dies out the sound and creates reverb.
2. EQ everything < Thats the most important
3. Mess with the knobs for little seshs and see what they change.
4. You don't have to use massive for dubstep, although it is the easiest, i use toxic biohazard sometimes as well.

Also its really good to have someone who knows what theyre talking about and is not afraid to give you critisism. I added a couple of artists on msn and they gave me some good pointers. Good job with the remix, you have great potential man ;)
