No, it's not the placement I'm unhappy with, I regret what I chose to be on my arm.
I got the band name Black Sabbath in the font of the Mob Rules album cover tattooed on my arm. I realized after I had done it its basically graffiti, and not only that, now it seems superfluous to wear either of the two Black Sabbath shirts that I have. I don't necessarily regret getting a Black Sabbath related tattoo, but I definitely should've chosen something besides the band name.
