Don't look at it under a microscope. Seriously. No tattoo is perfect. Your skin isn't a piece of paper. There's nothing wrong with that tattoo, but I would seriously evaluate your expectations. I don't mean this in an unkind way, but if you are expecting perfection, don't get any more tattoos because you'll never achieve it. Step back and look at the big picture, you have a nice tattoo, I'd just enjoy it.
