Took a bit to get this right, now we got Mulan, keeping it consistent with the previous ones based solely on her appearance in Wreck It Ralph 2,
Trained on AnyLora, so pretty decent compatibility with most semi-realistic/illustrative models
Setting the Lora to 1 may be lil' strict, I would play around with a range 0.7- 0.5 for best results,
(Unfortunately due to lack of outside supplemental ref I would recc on the lower-end side for lora weight, if extra material is found and new version would def be in order)
Triggerword is mulanodd, if details get lost just add some variation of 1girl, brown eyes, black hair, long hair, blunt ends and that should help maintain likeness
useful negatives are, blue hanfu, layered dress, red sash, and red jacket, letterman jacket, sukajan, white sleeves, white undershirt, black pants, pants,
or alternatively use those if you want her outfits from the film
Have Fun!
