That lead is very deadmau5y, I like it! I like how you use reverb for evolving the stab synth thingy, modulating the high cut of a reverb slowing can be an interesting effect for sustained instruments.

I think you would benefit from some subtle sidechain compression, nothing like house music where the sidechain is overbearing, just enough to allow the attack of your percussion through. And I wouldn't have it on all the time, because the attack of your synth is pretty vital in some areas.
