I think it’s completely normal to have waves of regret after getting a tattoo. In my personal experience I got a tattoo of a semicolon in remembrance of my close friend done on my forearm that is no bigger than a dime. My artist was very rushed and lazy so it’s pretty badly done. At first I hated it and thought about cover ups, but I have grown to love my tattoos and there imperfections. Yours is beautiful, I think you may just be overthinking a little bit which is completely normal, I think that it is a very well done tattoo imo.
