I started with Harley Quinn and just kept going. There's a version of Duela Dent I really like, so she was next. Plus, I thought she'd fit in with the other two. Last, I did a more curvy mature version of Poison Ivy. I was practicing body types and poses, then shading and brushes. Then I put in some Easter eggs, one blatantly obvious.
