Hmmm. Well this is a pretty subtle effect you're looking for. Perhaps I chose a bad image to use. Also, it was far enough away that it was hard to see what was going on.

How does this look?

I'm just grabbing images from the web looking for clipart that sort of looks like a tattoo. Part of the problem I have is that real tattoo artists use more gradients than this.
