man, go easy on compression, this sounds destroyed, even for dubstep norms.. for instance in moments like 2:35, the piano just can't breathe, same thing with that synth at 1:47
I think you could turn down the hihats a bit
and I don't get the right feel from the bass.. feels quite muddy.. there is some sub-bass in the kick but you should add it also into some melodic instrument.. you are probably boosting 100-200hz area too much, so sub frequencies around 50hz get lost.. remember the bass has to be clean and consistent, no bass boosts and sound goodizers are going to clean it
though musically it's kinda nice, the technical side really prevents me from enjoying the song
hope this helps a bit, gl with future production :)
