Unless this champion is not finished yet, i think you might have forgotten the mana gained on W, the duration on E and R's cloud duration. And its unclear to me if he can proc his own W debuff.

I realy like his Q but i think his E could be a little OP and unless clouded judgement has a realy short duration i think you should change the invisibilitie to just regular stealth.
