I get the sense the artist is throwing stuff at the wall and seeing what sticks. (Which I think is pretty bold, but I do also remember a bit of advice years ago which boiled down to "you don't need to share everything you make")
Dunno. I feel like if you've used an image from a reputable source under the proviso that you're licensed for it, and it turns out you're not... you may be able to blame Unsplash etc. and just swap the image out.
Cool is what you make it, dude.
