Use loRA on weights like 0.3 to 0.7

I saw on pixiv very beautiful drawings, and based on some of them to create loRA, it just so happened that in the dataset there were only bad examples of hands,because of that they look pretty bad,anyway the whole juice of this style is in the beautiful skin and eyes,so use promts to generate the face
Although if you can make hands look good, I'd love to see it
