Yeah I saw that a few days ago, looks #####in' dope.
...Looks good. Though along with what KPL said...the Joker looks a bit more like he'd fit in the first Evil Dead movie than Batman... though I'm not sure how he was originally designed in the comics and all. I'm probably just too fond of the original Batman movie (Not the Adam West one) in all it's old cheesiness.
Originally he was the Red Hood but, while fighting Batman, chemicals horribly disfigured him turning his lips red, his hair green, and his skin white. He went insane after that and became The Joker. So he can look like he does in Dark Knight and it's not a stretch at all. It's like having a different artist rendering him in a comic.
