The funny thing about these lion ring tattoos is that it's stupid to use a lion. Lions aren't monogamous. The male lion has a bunch of women. So this is like saying "yeah I'm one of the females this guy is sleeping with". Some symbolism, huh?
The more unique your tattoo is, more chances to represent you. Do not let other influence your decision. Just create it in your mind and then try to draw it or let someone draw it for you. That was you know for sure there is no one who has the same as you
