to keep close to her old design try any of these - or put in Neg to reduce chance
may need to add 3d, or realistic, in neg for 2d/anime - suggest weight between - 0.9 - 0.7
ILL / Pony xl TW - is morganxl, - does have some 3d influence
For appearance
MorgunYu, brown eyes, brown hair, short hair, or short ponytails or hair bun,
if using full helmet, remove all face related prompts
blue hair, in NEG if needed
for attire
gloves, black and red spacesuit, boots,
m.yu tag, - in painting helps, may also be keen on couches,
black tentacles, or other shadow entities, black slime, could possible be added (she can control it or be attacked by it) , if your into anything tentacle related this would be a character for that
adding skin tight, may reduce the width of the suit
PXL v3 - trained helmet somewhat compared to older version
