This lora pushes pin-up styles more toward a painted or drawn style. It also does a good job of changing the faces of the women to match that style instead of them having that Flux face.

It doesn't need an activation word, but it could make a difference, so feel free to use vintagepinup.

Update: I set the strength to 1 in the details, but the more I use it the more I think I prefer 0.8.
