Honestly, I found the entire mix to be really underwhelming.
There's not nearly enough low-end in general for dubstep, metal, or drum 'n' bass.
Your kick and snare sample are high and weak sounding.
The "oh yeah" sample was kinda cheesy, which would have been OK, but you repeated it way too many times. Along with that, the arrangement was a bit repetitive and tame as well.
I can see what you're going for here, but it really needs some work.
