Compositionally, this track seems to do everything you needed it to do for the genre. Sounds and feels dubsteppy!
3:54 - The lead synth here is WAY too bright. You could knock that back a good amount and it would still cut through the texture. Make sure after you rest your ears for a few hours to check your mix at super low volume. You'll hear things like this popping through the mix immediately.
Everything else sounds pretty good to me. Admittedly dubstep is not my thing but I can't subtract any points for simply being a genre I don't listen to on heavy rotation. Besides the aforementioned balance issue, you've got high marks. This is a great example of a dubstep track, but to get a score bump I'd like to hear something more uniquely 'you' coming through in this. You've got a good feel for balance, mixing, and form. You mentioned that this was 'generic'. If you want to bump this to the next level, I'd think about putting more of your specific personality into the next track (at least for competition). That said, well done!
