Thank you for letting me know. The source of the image goes to facebook's image database, though, so I can't go anywhere with that URL. =/ And I can't yell at people for getting it tattoo'd either. xD It's kind of flattering if they like it that much. lol.
If you can get me a name or URL of someone claiming the design as theirs, that would be appreciated so I can set things straight and at least possibly get credit.
[although, at second glance, the image looks less like an actual tattoo and more of a photoshop job... =/]
