Got it done. On my back. The thing is HUGE. I also (after getting the tattoo) realized that my spine is curved to the left. I found this out cause the guy doing it pointed it out. I looked in the mirror and although the tattoo IS centered on my back, from shoulder to shoulder, it is off-center with my spine (due to the curvature). Very interesting . . . . . . . oh well. It's centered on the back and that's what matters.
Look for pictures in a few weeks when it's healed. I'll repost on this thread when they're up (it'll probably be mid-january)
