Soles of Silk - oily yard

A popular shoot request is oily feet. Another popular request is dirty feet. Being the creative genius that I am (ha ha), I decided, why not combine them and see what we come up with?
Chrystine got to be the test subject for this theme combination. We were in the back yard and I had her walk around the grass and through some patches of dirt barefoot. She had just cleaned her feet inside, so they were a little damp and the grass and dirt clung to her toes and soles. When she got into the chair by the shed, she gave her feet a little brush off, and then proceeded to pour some oil all over those curvy soles and between her long toes.
I'm interested in seeing what everyone thinks about the combination of these two themes. I loved the way this set turned out. Maybe I'll do it again, but with really muddy feet or something. What do you think?
