I could actually believe frazetta might do something like this as a joke. There’s a lot of little bits that actually match his style enough to be believable at first glance. Doesn’t hold up to scrutiny, there’s too many little bits that don’t match for it to be convincing to someone that’s spent way too much time enjoying fantasy artists like Frazetta.
Like, if this had been a commission, and he did it for the money with constraints to his usual media of choice, I could see it.
