my main complaint is not with the fact that it's dubstep, or even that it's another generic "wobble ocremix" that have been flooding the WIP boards as of late. the arrangement is solid, the sounds are clear and bright, and the wobble is pretty creative at points
my problem lies with the drums. not the drum patterns, but the dryness and lack of volume. they sound completely neglected.
my advice would be to learn drum compression techniques, and even more importantly drum EQ settings. dubstep snares almost always have a large mid-to-low end punch, for example. there is a specific "thickness" (not to mention reverb) that makes a simple dubstep drum track perfectly accentuate the rest of the style, and this remix is distinctly lacking it.
I don't HATE this remix or anything. I was just really surprised that those drums didn't raise any red flags, and wanted to make some appropriate suggestions
