Very good start, needs a bit of tweaking
From 30 seconds on it's amazing, for the first 30 seconds there's a bit too big of a contrast between the two melodies, you should either lower one or higher the other and you've got yourself a great intro, it's all about the intro to grab the listener's attention and the rest of your song has the substance to keep them interested. I hear the difference in contrast at 1 min 40, the background synth at around 1:50 to 2:20 is amazing though. Definitely consider this a very good dubstep mix though.
Thanks Bro. I'm Not Really Used To Dubstep. I agree i need to get used to the organization.
This is actually my first.
I'll definately rework the intro for the final version.
