weight could be 0.6 - 0.8( makes it flexible ) - trained for 768 (can have better results)

to keep close to her old design try any of these - or put in Neg to reduce chance - SFW/NSFW

SFW - would be adding clothes - or removing the covered options, - this lora is very tricky to handle

may need to add 3d, or realistic, in neg for certain 2d/anime styles

PonyXL - duralxl

face/body

dural, bald, white eyes, or no pupils, - chrome body, or shiny skin, or silver skin,

may spawn with earrings, - put in NEG

it may be possible to add hair - it may not match skin though

suggest glowing eyes, hair, in Neg in some cases

Outfit - is always nude

adding none of the NSFW options - and clothes, bra, in NEG - may result in more accuracy

nude, covered nipples, covered navel, covered pussy, toned, or colored nipple options,

adding nipples, pussy, in NEG may reduce the effect - making it less strong and more silverish with rest of body

there's loras that focus on skin colors alternatives somewhere on the site

adding clothes may be possible - was not trained in anything specific
