Ok, so update on my choices thus far.
Earth: Lesser or Mojave (still deciding there)
Air: haven't decided yet here with anything yet, but a pied might be best choice
Fire: looking for something really orange or red here so still looking
Water: mystic potion just screams water to me
Light: albino
Dark: Axanthic

My reason for these light/dark choices is that while a BEL and super black pastel fit the bill to a T, I think they would be really hard to show off properly in a tattoo. I think something with a little contrast will work better and I think these 2 balance out really well. What do you guys think so far?
