Yes no outlines at all, the picture reference is from A Book of Skulls by Victor Modafferi, it is a dark pencil sketch, and the client wanted me to get as close to the rough sketchy look of the drawing in the book, so no outlines or fine details, all done with this needle:

@Alie
It is a sketch book / inspiration book, thats why the tattoo looks "rough" the client wanted that look on his tattoo, here is a link to the book, but just google the title and you will find that they sell it a lot of places:
