Used kohya_ss gui.
Here are some parameters and helpful keywords:
• Checkpoint: AbyssOrangeMix3
• Trigger Word: ayeka
• Weight: 0.75 - 1 (lower weights might be preferable, samples are using 0.75-0.85)
purple hair, red eyes, obi, japanese clothes
( Hair details might be difficult to form, and prompting twintails doesn't seem to help. I will experiment more with this and perhaps release a V2 in the future. )
To produce similar results I recommend EasyNegative, this negative embedding was used in the sample images. I'm also using Clip Skip 2 and hires fix.
