What kind of being are you—a human or a machine? The tattoo is pretty awesome when you think about it. But, much like the skull that rests atop his head, we are certain that at some point in the future, he will question what it was that he was considering at the time. Concerning the skull, I don’t think it fits in very well with the rest of the artwork.
It appears as though this could be the beginning of an odd assortment of facial tattoos based on its appearance alone. It’s possible that all he needs to do is acquire an attitude of gratitude toward what he already possesses and then move on to tattooing other parts of his body.
