Your Joker looks a lot like Nicholson from Burton's Batman. Was that intentional? I love that you've not made Batman a hulking block, here. Cracking image / cover, this one.
Awesome job on this!! I've read the original story, I have the DVD adaptation (which I'm guessing by the Joker's design is what you were trying for...and succeeded!), and this is just fantastic!
