I enjoyed this for the most part. Interesting composition and melodies. I'm incredibly jealous of your dubstep synths, I have no idea how to do things like that. (Well, I have an idea, but I don't own the recommended plugins, sytrus/massive) Only suggestion for them is to add more sub bass. (the entire track feels like it's lacking in sub, but the dub synths need it the most.)
As far as criticisms, the snare feels.. weird? It really reminds me of the FL Default snare. (I'm 90% sure it is after an A/B compare.) I think if you changed the sample and added some reverb to it, (in certain sections,) the track would sound a little more authentic. Also, your sidechain release times on one synth feel WAY too long. (It's longer than it needs to be to make the kick stand out. It doesn't really suit the tempo i think. If you're using Gross Beat, learn how to use Fruity Limiters side chaining features. Use a BPM to miliseconds calculator to set your release time to the desired length.)
In the intro I didn't really like the side chaining, I feel it was a little too extreme. That's more of a personal preference than an actual flaw though.
Overall this is relatively well made, and relatively a enjoyable tune. (Decent mix and master by the way!) Keep up the good work.
