An anonymous reader writes, “I am a computer programmer and amateur herpetologist. On my leg is Henry, a North Brazilian Boa constrictor — rare in captivity at the time. I brought him in for photos before we began, and again after it was completely healed. As you can see in this photo, his colors were altered in the tattoo to stand out better. It took 20 hours over the course of 14 months to complete and was done completely freehand. Each scale was drawn individually. This photo is so special, since he’s posed very much the way he came out on my leg, tongue and all. It’s not like I could give him instructions on what to do.”
