I got a dragon that wraps around my chest, arms and shoulder blade. It was a custom piece that took a total of 10 hrs of inking-3 sessions, 3 months to complete (have to wait for it to heal after each session). I work in a corporate environment and the only people that get to see it are the ones that goes to the same gym as I (my boss seen it)-No biggie for him (don't care either way).
After design is decided on, I think size and location is also very important. Another thing, tattoos are addictive, I am fighting the urge to add-on or get another one.
