Works fine at :0.8 and clip skip 2.
The examples images are just text2img(except the first that was made with the sd ultimatepscale extension), if you use hiresfix or impainting you can obtain better results.
Psdt: in the example images i forgot to add 1girl, solo tags, but are recommended.
Tags:
Eyes: ringed eyes, and red eyes or orange eyes.
Hair: single braid, hair over one eye, black hair, or short hair and hair between eyes (for her first appear in the manga)
Clothes: just use sweater or turtleneck, and add tags to modify it at your taste like long sleeves, bare shoulders, short sleeves, etc.
I was trying to make one of nikaidou from dorohedoro but i don't like the result.
