Back when I was in high school, I would often paint my face before going to school. I figured it was something nobody else was doing, so I'd be able to separate myself from the crowd. One of the designs I would give myself a lot of the time would be this one which was split down the middle of my face, with colour-negative stark black and white mirror-image features on either side.
As much as I loved this scheme, though, I've never used this scheme in a body painting design up until now, but with this model, it seemed the thing to do. I didn't realize how weirdly yin-yang-ish it would be until I saw it in action, though.
