to keep close to her old design try any of these - or put in Neg ( when altering appearance/outfit)
may need to add 3d, or realistic, in neg for certain 2d/anime styles - lower weight for less 3d influence
PonyXL - may need a XL VAE - Images "may" be - at or past 1024x1024 or 832x1024 - Sampling steps past 30 - this can work with any model that is PonyXL or was merged/trained from it - This was trained on civit so its not as good as outsource training
face/body
Ephemera, black hair, black eyes, long hair, - black lips, -
facial mark, or face strap, or straps attached to face, - results may vary as they may be confused as tattoos, or messy make up, - a XL lora version may fix this issue perhaps in the future
black sclera, if it helps
vampire teeth, or fangs, results may vary
skin may alternate to pale or grey skin
Outfit
choker, necklace, corset, detached sleeves, black leotard, fingerless gloves, boots, or thigh boots,
suggest these in NEG if altering or NSFW
cleavage, or cleavage cutout, may help
