Pretty cool! I like the schmancy chords! I don't have a lot of critiques, but I do have one, and I'll put it bluntly: the balance isn't good. That's not to say that you can't learn from your mistakes though. Just don't take what I say personally. :P

That being said, balance issues can arise from one of two things: lopsided volume or lopsided/lack of mixing. (I know that volume is part of mixing so saying that is somewhat redundant, but in this track, they seem like they should both be focused on individually.) It sounds to me like the lopsided volume is persistent throughout the whole track, and the lopsided/lack of mixing is in the drops. With the volume, I would think it's somewhat simple - turn up stuff that you want people to notice, and turn down the background stuff, just as a general rule. As for mixing, if you don't already know, mixing is removing conflicting frequencies between different noises so that 1.) they sound better together and 2.) one is more prominent than the other, typically. So for dubstep, highpass the hats and background arps or whatever's happening up high, sidechain the sub bass with the kick, and remove frequencies from anything else around 250 Hz to bring out the snare (or whatever frequency the snare hits at), including the basses, leads, and background chords. Then, just adjust volume 'till it sounds good.

So yeah. Crazy stuff, but I think you can get the hang of it. :)
