I'm all for tattoos, but for tattoos that revolve around fandoms (TV shows, anime, video games , etc.) I would have to be insanely careful for it to have personal relevance to me years later. I really shouldn't be one to lecture about tattoos, since I got one when I was 16 but I'll just urge you to be careful. I myself am considering a Mass Effect tattoo for a new part of my life, but anyways. Why Celebi and why Kingdom Hearts? Where are you thinking of getting them?
@ the mario tattoo oh my god I couldn't handle that on my wrist it's too visible what if I went for a job interview or something.
edit: and speaking of new looks, I'm going to grow out a beard and maybe get a lip piercing.
