If you have OCD, do not get any other tattoos. You are going to drive yourself crazy. Tattoos are made by humans, and humans aren't perfect. There will always be things you see as "imperfections," and obsessing over them is not healthy.
It looks fine. OCD is a great way to make a good tattoo worse. Trust me, NOBODY is eyeing your tattoo with a microscope except you. Enjoy it and get more tattoos.
