Hey guys, i don't want to talk much, so this is why i'm here: I want to become awesome in production of dubstep and synthesizers in general

Because i can't afford other stuff, i'm using Reason 5.0 and Cubase 5.0 for production right now, creating all the synths in the rack myself. The problem is that i feel like i reached Reason's limits already. That's why i'm thinking of buying NI Massive soon. Well, anyways, this is one of my first 'better' attempts of an original dubstep track.
I'd love to hear some feedback, may it be about buildup or taste or technical stuff (which i need the most in my opinion)!
This is the WIP:
