The images above are "after > before".
Suggested usage with WAI-illustrious-SDXL or other flat, anime-style ones.
In theory, it should improve details, background and foreground separation, character focus, eyes, lighting, shadows, color, depth of field and composition, generally making women sexier.
If you have a preferred style, keep this at 0.2-0.4, or it will clash with your style. Otherwise, I think everything up to 0.8 gives good results.
Weights over 0.8 will start changing the style too much, as well as composition and details, so use with care if you aim for prompt consistency. Can still be used to improve details and lighting for flat anime colors at ~0.6.
Weight above 1.1 starts face deformation and other bad artifacts, not recommended.
It should be biased towards non-kid-looking women, slim waists, big breasts, and wide hips.
