I met a girl once who had a gorgeous tattoo on the inside of her forearm, near the elbow. I think that's a nice place for tats on girls.
Anyway, she had her two Siamese cats drawn very softly and quite stylised. They had very pretty eyes, and diamond colars. The shading was gorgeous, and the whole thing was very delicate.
I don't have any tattoos myself, but love them on other people.
