I've been watching a lot of Batman: The Animated Series on DVD the past few weeks, and I noticed a few patterns. It may surprise you to know that I don't think I've ever drawn the BTAS model for Batman.  Never ever!  I think I started doodling animation-style Batman with The New Batman Adventures, after they'd redesigned him to look Super Awesomer.  That Batman just really wants to be drawn.  I can't help it.  Drawing the original animated Batman for this strip was a lot harder than I thought it'd be... I have the later version etched into my brain.  I had to forget I was drawing Batman and pretend I was drawing something totally new.
