I have a few tattoos of my own, and I want SO MANY MORE.
Got this Japanese Beetle by Tiffer Wright in Dallas, TX a few years ago.
And this one of Sailor Moon's transformation brooch and Tuxedo Mask's pocket watch by Kimberly Reed in Savannah, GA just this summer.
I also have an Enso tattoo on my wrist by an artist at Ace's Tattoo in Denton, TX ages ago, but I don't have any pictures of it at the moment.
My next tattoo is going to be an armadillo eating a sandwich, hopefully from Cory Hand in Savannah, though we'll sort of have to wait and see what happens with money and if I can get an appointment with the guy.
I'll give my characters tattoos sometimes, though not very often, partly just because it is kind of a pain in the butt to draw them all the time. When I do have a character with tattoos, I usually draw the tattoo as a separate image, and then copy and paste it onto the character and use the Warp tool to distort it to fit the shape and curve of their body in that particular shot.
