1) Listen to your artist.
2) Chill out.
3) Learn from your mistakes. You don't get a good tattoo from a shit artist. Good artists aren't cheap.
I see way worse than that every day. I'm not even sure what is so horrible about the work. If I saw that on the street I wouldn't give it a second thought.
If you can't get past this, don't get more tattoos. See #2 again. 😉
