Circle Of Life Enso tattoo. Zen Buddhist symbol of enlightenment, clarity, balance and life.
Logan's tattoo that was mentioned in Chapter 5 of Too Bad For His Own Good, was a skull. This is kind of what it's supposed to look like. http://www.wattpad.com/56166455-too-bad-for-his-own-good-spin-off-of-a-guy-best
Not usually a skull guy but I like this one for some reason
