Here's an animated .GIF showing the process of how I created my recent 1940's esque pin-up of Poison Ivy [link]
Since I'm a big fan of the 1990's "Batman The Animated Series" I wanted to take the simplicity of that costume and bring it to an older pin-up style. I think this works well since the whole series had the feel of a 1940's Noir style film. However, I did change up her hair a little bit; I wanted to do something a little bit more rockabilly than her hair style from the series. Anyways I hope you enjoyed it and maybe learned something from my process.
By the way, if you haven't you should buy the animated series [link]
it's the best! Thanks!
