Yo bro, Not bad eh. My first point would be the drums.
They're too... natural? I dunno how to put it, but they need to be a fair bit louder,
and I suggest choosing a more synthetic snare, for the more brosteppy sorta sound you're going for.
Also, when that bass comes in at about 55s in, it dominates the frequencies used by your kick drum, drowning it out. Some EQ-ing and a spectrum analyzer are in order! haha
Also, try to variate the LFO sync more on you wobbles, try for 8th's, 12th's and 16ths, as the bass in dubstep is also a rhythmic element, as much as a music one.
I mean, like, your synth use is fine, it's your percussion letting you down here, you need to work on your drums.
Hey, better than my first track
