Retro Big Naturals - Photorealistic

This LoRA has been heavily baked. I recommend using it at 0.7 -- it'll definitely artifact up higher. And it's fine at 0.4-0.6 as well.

Most realistic models tend to work OK, but gotta say that Art + Eros tribute seems to really jive with this LoRA.

The keyword isn't required at all, but you may find that using the retrobigguns keyword helps here and again.

Depending on your taste, but I have to say that the prompt word thicc seems to work awesome with this one. Bigger boobs usually means bigger women, and they fit so well and look better. But, to each their own, you do you.
