There's a few things here that tell me it's probably not copyright-theft-generated. The big one that's easy to explain is the tail. The tail starts off from behind the mouse, snakes in front of the cloak and background (so far so good), but then, here's the critical thing, passes behind the fern staff and continues on the other side of it, positioned properly and in continuity.
Copyright-theft-generators have tremendous problems with this because, as the chorus goes, they don't understand anything. There is no mental model of "a tail" with them. There is no thought of a tail's properties, so keeping a tail contiguous while passing across barriers is very hard for them.
Especially if the image is poisoned.
