I looked at the artist's social media bio and from my understanding of it they are now making things using AI gen. Which I also see there are some deleted items on here also tagged with AI under their name. So I think it's safe for me to tag this as AI.
I checked the artist. Saw some of their art posted here. Didn't see the notice from site telling me the artist is AI prompter. So I posted it. An accident. Not the first time happened to me and probably won't be the last.
