To be clear, the piece of art I was commenting on is not one of the known AI pieces of Art. It is in fact a MtG card art used in the new DnD Beyond supplement. So we don't know if AI was used at all.the AI did not generate the image, it used an existing sketch to ‘enhance’ it
Regarding the AI art in Bigby's: yes I know the artist used the AI to enhance their own sketch. I even posted an example here: post #12 a good 28 posts before yours!
