I wanted to do some night scenery, but the models didn't want to cooperate. After some unsuccessful results, I've chosen Autism Mix SDXL model with IDW style for some reason. All I can say is I didn't expect this kind of outcome.
I've used it as an img2img base with 2048x2048 resolution instead of regenerating it in 1024x1024 (or similar resolution) and upscaling. It greatly improved Luna's face and got rid of the artifacts. After some manual editing, the final picture has been created. I thought that it would make a cool wallpaper, so I tried my hand at outpainting and created an alternative version.
