Poison Ivy by Bruce Timm
One of my all time favorites Mr. Freeze by Bruce Timm
Bruce Timm's rendition of Raven from Teen Titans. This man is a comic and art legend. Strong use of black and white.
The Joker by Bruce Timm (Also proof you're a 90's kid. You see this and think "Mark Hamill")
Batman By Bruce Timm
Batman: The Animated Series - Poison Ivy
Wonder Woman by comic_art_fan
Buffy The Vampire Slayer Cast by Bruce Timm
