If you have really incredible ink which works with the contours of your body and which you got because it is meaningful to you, that can definitely be a visual plus. If you have a bunch of generic flash or some meaningless large piece you got because you thought it would make you an altmodel, we will pass on that. If you have jailhouse tats, then it comes down to whether you have the attitude to pull them off. If you have no tattoos at all, that is fine too, so long as there is something interesting, unique, beautiful, and maverick about your look.
