I made a bunch of images in the style of Raita and used those to try and generate several images of the upturned/retrousse tits with and without puffy nipples and trained a lora on those.
It seems to have worked at making the tits bigger and more upturned at the nips, but also has had the side effect of affecting the hair too much, dropping the viewpoint lower, and also making the lighting brighter.
I'll work on fixing those issues and post an additional version later.
No clue why but it does NOT work on Civitai generation, so I turned that off. Maybe it really just does need the Big Love model, which is unavailable.
