I posted these images in an earlier post, but I've done a little work on them since then. Above is the color version of the Poison Ivy illustration. Special thanks go out to Nicholas Straight (blog: Drawmit!), who did a preliminary color design that helped me formulate the final colors. And below is the Two-Face illustration, which originally had three tones in the background. Thanks go out to Jordan Delmundo (blog: Brown on the Towne) for the recommendation!
