Just remember than the bigger in details your tattoo is, the more expensive your tattoo may get, depending on which tattoo parlor you go to, just keep that in mind.
I've seen people use this guy too. A unique way to express is to write quotes in different languages on your body too. Maybe you can try mixing tattoos? Maybe mix several different tattoos in one type of tattoo?
