"The Clown prince of Crime", "the Harlequin of Hate", "the Ace of Knaves", "the..." you know what? Forget it.
Let's face the facts, the joker's the greatest villain of all time. If you don't know who he is, not only are you not going to download this, but chances are your learning disability prohibits you from reading this.
For this skin, I tried to get away from the cartoony-look a bit and add some realism; which is why the normals make it look like his smile is indented and scarred (for those not in the know, his "smile" is the result of his flesh being searing by a chemical bath).
Also, i know that the screenshots make his purple suit look a bit under-detailed, but that's not the case. Both the skin and Normals are hi-resolution, and work together very well to bring detail to him. (obviously the shading that comes from the normals isn't going to show up well in any screenshot)
