When I see green, orange, and purple color pencils on my desk, I say to myself, “Damn, I should draw the Joker.”
So, I drew the Joker:

You can probably tell that my idea of the Joker is heavily based on Bruce Timm’s animated version, with just a dash of Brian Bolland thrown in.
(This Joker is not intended to go with the timeline I have imagined for my “Sons of the Bat” re-designs, but I imagine I will use this as a basis for a future Joker if/when I get to the villains of that era!)
