Here are the tattoos I created for my main Sim, Marc Panda. 
There are 2 tattoos :
-The first one comes from the game Star Wars - Knights of the Old Republic (KOTOR) and it's the tattoo worn by Canderous Ordo on his left shoulder
-The second one are tallies on the back, each bar represents a military victory for my character
