Created with Pixai.art. Went back to fix Insomnia chan's lora since I realised I had used old and latest images of her for the training images. This time, you'll be able to generate her in the artist's current style without trouble. The best strength i would say is from 0.5 to 0.65, from what I have experienced anyway.

Probably best to put the term "long hair" in the negative prompts when genning.
