Can't go wrong with Red Brinstar as a source.
Beginning synth feels exposed. Some more atmospherics would be good.
Synth at 0:36 feels very loud and exposed. You need something more here, and turn the lead down a lot. Part at 1:06 feels quiet and weak compared to the loud synth that comes before, when it should punch you in the gut.
Would like to hear more bass freqs in the center. Your synth bass is spread out very wide. Just my personal feeling, though.
Lead synth on the whole doesn't feel very expressive, some vibrato could easily take care of that.
I feel overall you could beef up the track with more layers. As I noted earlier parts of it are too sparse.
Just my impressions. I think this has the makings of a good dubstep-ish type track once you finesse it.
