You don't even need to write any positive prompts to create beautiful girls with this model, which was created with many photos and many stages. I've included a few comparison charts below to show how it differs from some other realistic models.

1) No positive prompts were used in this comparison.

2) In this comparison, only the word "2girls" was used as a positive prompt.

3) In this comparison, only the word "3girls" was used as a positive prompt.

I use ADetailer to beautify faces.

I also find it useful to use negative embeddings such as instarealneg, SkinPerfection, np_simple_negatives.

I use Color101VAE but you can try different things.

Setting Clip Skip to 1 gives more successful results.

Good results can be obtained at resolutions such as 384X680, 416X624, 440X584, 456X568, 512X768 and 640X960. Or vice versa for horizontal images... But the success rate may decrease slightly for horizontal images.

I definitely recommend using Hires fix, but set the denoising strength to a value around 0.1. When you increase the value, facial expressions change a lot. Of course, if you use ADetailer, you can increase this value as you wish. ADetailer already adjusts the faces itself.
