Baby Tinkerbell Tattoo

So I was asked to come up with a "Baby Tinkerbell" tattoo for someone I know, and here's the result. The original request was for her to be a baby in diapers, tho I did want to provide the option of Tinkerbell's traditional costume as well. I wonder which one she'll choose?

Drawn in pencil, but digitally inked in Manga Studio.

Here's a quickie mockup of what it might look like colored on skin:
