Snake tattoos are good because they're easy to get creative with. I considered getting an Asclepius Wand (not to be confused with the Staff of Hermes). It's a gold rod with a single snake wrapped around it. It's said it's the true origin of the Hermes staff worn in by the those in the medical field, but I like the Biblical version of it, myself (even though I'm not religious in any way). Moses was commanded to erect a gold staff with the serpent on it and it would heal whoever looked upon it.
I'm also fascinated with Angels for some reason, so I'm looking into something there.
