"Holding a pillow" was originally Billie's pin-up art idea, but I discarded it and used it for Amber instead. They're basically built the same anyway. I think the pose suits her personality better.
At this point I start shading my figures with colors rather than de-opaqued black. It takes a lot longer, which is why I don't use it in my strip, but it looks a lot nicer when rendering skin.
Amber is super shiny.
