I'm still a little butt-hurt from the New 52 retcons but to me, the Court of Owls is probably the best villain to be added to the Bat rogues gallery since the classics. Their design is iconic and the way Scott Snyder introduced them was great, he has the perfect writing style for Batman. He just... gets the character, between him and Capulo's art I haven't enjoyed a main ongoing this much in a long time. :]
Also want to note that this piece was inspired by Djurdjevic's amazing cover for Daredevil Issue#100
Someday you should do a piece with the original characters for the TV series. I caught an episode on cable the other day, it was so much fun to watch. I was just a kid back in the sixties. We watched Batman on a 19" black and white TV.
