I only have one, a butterfly on my ankle... it's cute, and my favorite colors (purple and teal) but it's tiny and I really want another.
For a while, I wanted a very specific tattoo but couldn't figure out how to find someone to do it (or a good picture of it)... that fish from Fantasia, from the Nutcracker suite. Kinda goldfish-like, but with pouty lips and long eyelashes. Someone recommended basing it on a picture of Chloe, from Pinocchio, but she's more cute and less sexy, heh.
Now I want something with multicolored stars. I saw a show that was talking about some of the women on the Suicide Girls web site, and one of them had these rainbow stars, I think on her forearm, all different sizes, with thick black outlines and each filled in with a different color. It was adorable.
