Spinal Tap

To make a long story short, I'm trying to do a series of these 'back pieces' on different girls. I think there is an air of piquing curiosity in this project. Also I feel it has its own risque elements that make each picture a little more captivating than others that I have previously created. This is due to the fact that the images were not edited, and the drawings on the girls' backs are real. I did them by hand, all with a black Sharpie marker. Does knowing the process pique the interest?
