It's...bad...
Seriously, the Joker has to dress as a Joker but this is just 'edgy delinquency' level and not Crazed and Extremely dangerous supercriminal level.
My favorite Joker design so far has been the one from the Arkham series, mainly because he does look like a joker but we instantly know that he is dangerous from his inhuman looks alone:
A larger than life super criminal made right.
If we take games out of the picture then the Dark Knight joker sweeps the field and this quote explains why:
The Dark Knight joker had a quality that no other Joker ever had. He was human in his madness and as such far scarier, which is why he carried that movie at all times. The problem with his design is that he doesn't instantly register as extremely dangerous but that highlights the glory of the character as the story develops.
