Amazing concept. It looks both grotesque and kind of cute. You have great skills with ink and watercolor. I'm on the fence about the colored pencil. I don't really like for the texture of the paper being visible. However, it does add an element of "sketchiness" to it.
Yeah, almost every work I do ends up being some sort of experiment. I've gotten better at integrating colored pencil in with other pieces lately. Just adding bits where I want the color to shift, or create a streak of a specific color.
