These are some of the best I've seen for being of traditional style as guarding the front of a building. But they come in pairs, M & F, and should have different faces. Mouth open for the M, mouth closed for the F. If it were a full lion tattoo, there would be differences in the paws.
Could you modify these examples to be on the chest ? L & R are different. I already have a dragon & a tiger on my biceps.
