to keep close to her old design try any of these - or put in Neg to reduce chance - SFW/NSFW
may need to add 2d, or anime, in neg for certain 3d, or realistic,styles due to having more 2d image training - or lower weight of lora for less 2d influence
has 3d training from later games as well but can still work with 2d
PonyXL - Tw is ladyfighterxl, - may update later to v6 which should improve accuracy
iLLxl - TW is ldyfgtrxl,
For appearance
Valkyrie, pixie cut, or short hair, - green hair, green eyes, pointy ears, - brown headband,
you can change hair and skin color more or less - but other colors in NEG if needed
for attire
bare shoulders, armored thigh boots, or greaves, bike shorts ,midriff, beltbra, belt buckle, or brown belts, or belt, sleeveless,
could add strapless, if there is a normal bra, - or underboob, could work
would add, belt bracers, in prompt and put gloves, in NEG
has thighhighs, if no greaves,
can more or less change the color of gear - is easier with the weaker versions
suggest green attire, in neg in some cases
