Intro sounds very "housey". I think it's mostly because of the kick on every beat, rather than utilising dubstep's general half-time kick snare template. But I like this little hybrid :) The dela-drenched pluck sounds REALLY nice. It goes very well with the bass and arpeggiated synth.
I didn't really like the chorus. I think you've mixed down that section well, but forgot about the stereo image. Everything seems to be coming from the centre of the speakers. I think it might help if you just added a bit stereo delay to some of the synths to make them more distinguishable. Also adds some excitement and variety would you believe!
The chorus is a bit choppy too. Try overlapping the synths rather than cutting them as soon as the next one plays. Try recording live. Always helps to make your music sound more humanized and not as choppy/robotic. Try playing with the attack of your chorus synths. Medium attacks (when sidechained to the kick) sound SUPER heavy if triggered at the same time as a kick.
So far, I'm impressed with the intro and your mix. But the sounds a bit awkward. Maybe give a splash of reverb a try too! ;)
Awesome work! 4/5 7/10
