You could have paid someone to make one for you or just picked a different image to use. At absolute minimum you could have cited that it's AI instead of letting people believe it's an artist's work.
It looks generic and junky, I could tell it was AI from one glance, before I even noticed all the errors.
Because now I'm also wondering what else on the site is AI and how much of your writing potentially is. And that makes me less likely to want to visit.
