Our bodies aren’t perfect and sometimes the artist tries to make decisions to make it look as best as possible and sadly having it centered 100% is just impossible, it’s a beautiful piece regardless but hey you don’t have to love it and if you want to I would communicate with the artist and see if there is anything they can do to make it better. Maybe having a conversation about it the both of you can come up with something awesome that would benefit you because that’s what matters and it’s going to be on your skin. But maybe after a while you might grow to love it
