First of all, this song is just kind of middle-of-the-road. Don't get me wrong, I know how long it takes to get to middle-of-the-road level, and I commend you for the tenacity you must have, but at the same time, it's good to know what to work on.
With that in mind, the biggest problem I spy is instrumentation. This is pretty simple, especially for electronic music. The idea is to have something playing in the three main ranges at all times, the ranges being low, mid and high. But, at most, you want only one instrument per octave. In my experience, the kick and snare don't count as "instruments" when it comes to that, but the hats do, as long as the hats are fairly constant.
Usually though, I use that rule to say, "this section doesn't sound full... oh, there's nothing in the low end." I don't usually have to worry about too many instruments.
Another thing: mixing. Dubstep is probably more simplistic when it comes to mixing, honestly. The biggest thing to worry about is the presence of the kick and snare, because they add so much to the energy of the track that you want them really loud, but not distastefully loud. Because of what compression does, in order to have a result where the kick and snare are at a properly loud volume, you need to have them rather ridiculously loud in the premaster. It sounds like you didn't do that very much. I can hear the sidechaining, but that's not going to cut it in dubstep. xD
Finally... 01:36... Wubbix's Spag Heddy tutorial much? xD
Really though, a lot of being an artist is stealing other peoples' stuff. It's not like ideas have copyrights on 'em.
Overall, alright. Just keep plodding along.
