a little shakey
this doesn't sound exactly like dubstep, but i know it is. the bassline it has is just different than others, its not one of those phat rock-your-melon basslines.
this really is good, but the frequency of the bass seems to be a bit to high, doesnt sound like bass, just some slow type of sine/synth.
though i didn't let that deter me from enjoying the song, this is a good song. hit up a lower bassline and see how that works :)
Very good job otherwise. Every dubstep artist has their own style and what they like to hear, so if this is your style, stick to it. It does sound good.
