Realllllly funky dubstep going on here (good thing). The drop has such an awesome groove and although the "yug yug" synth is heavily over used in dub step you've put a nice creative twist on it making it original so great work there!
My snag is to do with "Beefing" up & having a cleaner splashier snare as it disappears a bit now and then. Bass made my speakers go mental though, great job dude!
