Nice one, surreal!
And amen to what crystaldragon said about the painful areas. Another place is the sof skin that doesn't see much sun, like the insides of your arms.
One of mine comes in toward my inner arm. The closer the artist came with the gun, the worse it hurt. My boss recently got a band all the way around one of his forarms....he's a big tough guy, and he said he was fighting back tears!
I'll see if I can get some pics of mine sometime.
