Empathy
A big premise in my reviews is that I don't care about what score I give to you, because I care more about the words I say.
So 10 out of 10. xD
This track is very unique in my opinion, the way you mixed various styles into one major structure. The transitions sound pretty smooth and there's definitely a good flow in your song, from the edgy trembling synths to the wobbling bassline typical of Dubstep, to the raggae-like groove carried throughout the three and a half minutes. I feel however that some parts still need some polish and better EQ, as I can hear overcompression problems dealing with the bass frequencies and indeed the kicks. Although the main theme sounds a bit generic and it's repeated twice, it still sounds refreshing enough for a re-listen. Next time you could add more themes and, possibly, instruments in order for the track to be even more enjoyable.
Take your time and you'll succeed. :D
