Hey there! I hope you're having a good day so far, and I'm really sorry to bother you at an hour like this, but I've noticed that you've used one of my art pieces for your story 'Number all my Bones- there and back and there again'. For reference, I'm the same LimeGreenForest on Deviantart and the same ViridiAve from the GT Amino.
Usually I let stuff like this slide, but this particular piece was commissioned to me by another writer from AO3 named NazarethRose. I cannot allow any other person use this for a number of reasons- mostly because they're the ones who paid for this piece.
I really would appreciate it if you changed the cover of your novel (great writing by the way). And hey, if ever you need a new art piece for it you can just ask me for one. There are several other options available to you and I'm more than happy to help you with them.
Again, I'm so sorry for this... wall of text and reprimanding, and I hope that we come to an agreement soon!
