Are you sure this is AI generated? It doesn't look like it is.
I checked the profile and it seems some people accused that person of using AI for "Tracing" also the profile says that "likes to experiment with styles". So maybe it is "Ai assisted". Also I do think this image does looks like AI as well (I don't mean to criticize the process from other people nor this person by the way just trying to clarify and give my point of view)
