I am so bad at figuring out if stuff is AI or not, but the image's melty style and dark fantasy vibe, which seems popular in Youtube AI vids right now, made me think it is AI.
At the time, the video he shows of him painting it proved to me it was real, that and the account was 9 years old, so I bought it. Since then tho, my wife pointed out to me that AI video is crazy better at faking things than I had thought at the time.
Now I have the purchased print at home (wasn't too expensive thankfully) and am undecided whether to hang it or not. Love the image, but if it is AI that will just make me feel gross to have it on the wall.
