Love the intro!!!  Breaks, Ambience and FX are really good, throughout the song!  Really like the samples used, even though its more chilled than what I'd typically listen to, which is v.interestin Only thing is you should probably add a light-synth/distortion to the bass so its not just sub cuz it seems barely noticable.  I can feel it more than I hear it, is that what U intended?  i had to turn my sub up either way.  Otherwise perfect production for me!
