So for this model I recommend 0.8 -1, however, there are a few tags that you may want to remove if you are not using the traditional outfit:

If you do not want the traditional outfit then put these in the negative; overalls, jacket, overall shorts, : And in the Positive put: exposed arms, exposed legs,

It can be kinda finicky if you do not do that.

Try this for the positive as well: hackerling, 1girl, overalls, horns, pointy ears, solo, blue hair, virtual youtuber, twintails, jacket, overall shorts, black eyes, official art,

And try this for the negative: text, logos, small hands, simple background, black void, stretched, elongated, multiple women, bad anatomy, bad hands, bad fingers, too many fingers, multiple girls,
