Heh. This was fun. Other than Ole' Harley Girl, I'd never actually drawn of these guys before which is odd but not unusual for me now that I think of it. There are tons of characters that I love and I've never tried my hand at... come to think of it I've never tried drawing Catwoman before either ;)
Thanks to friend and fellow Artist Jason Flowers for the feedback on Mister Freeze, I'm thinking there's a big difference between the pencil and ink stages so hopefully more of that cold heartedness (wink) comes across.
