Here's a sketch I did of the Joker. I'm working on my interpretation of his look. I want to make sure he looks like he's got a permanent grin. I don't want him to look like he's making a conscious effort to grin. As far as his dress and grooming, I think he may look too disheveled. I think the grin looks good, but I might do some research to make sure I've got the best look.
