I played around with some in-painting. The results are not perfect (the face is a bit too sharp compared to the rest of the image), but in general, I think it's quite good.
I used Fooocus with razzz-realismEngineSDXL as base model.
Prompt:
emma watson, sultry, sexy, seductive, makeup, black hair, looking at camera, (grainy), bad quality
A couple more...
Base model: razzz_sdxxxl
Prompt:
emma watson, sultry, sexy, seductive, sensual, makeup, smokey eyes, ((dark brown hair)), (messy hair), wet hair, (grainy), low quality, detailed eyes
Wow, upscaling using the base models provides amazing results. I've tweaked the prompt and then upscaled the image 2x :D
