Wubwubmubmub RAWWR!
Yay for dubstep :)
My thoughts?
Intro is a bit dragged, and ... eh that piano-ish synth (the bass) ... don't know how I feel about it. Maybe with some percussion brought in before the drop it'd work better... yeah im thinking that could really fix this up.
As far as your wobbles.. Very evil sounding >:) might suggest not using the same LFO pattern for the whole song. Most songs now have (... well maybe not most, but ones i like) like 16 bar filter cut patterns, or they change it up each drop. Somethin to think about when you get there.
Hmmm.. Bring up your drum levels a bit. or try layering multiple drum tracks under different filter settings. Might make them sound fuller. Ideally you want to master each drum seperately. ^_^
Definitely see the epic feel in the intro when the strings come in though. I might do a really high slow pitch slide or a static fade in before thedrop.
Anyways yea :) hope this gives ideas!
