Dude, this is one of the most realistic drawings I've ever seen of the Joker! The author comments summed it up perfectly. It's still more than that. It's an awesome drawing of the Joker. I can't tell if this was based on any specific actor who played him. I guess I'm just thinking of Heath Ledger because of the Dark Knight movie.
When another popular Joker comes around, I might think of him instead. The best part is probably the grin. It really does look like his lips melted off. You show such strong facial expressions too. The different hairs are all detailed wonderfully. One of the best Joker pictures!
