They were made by putting the original starsector portrait in img2img with ~0.4 denoising.
I used Arthemy Comics v4 model found here;

That allows me to raise the denoising (more AI freedom) while still keeping the original structure, as I wanted to keep it vanilla-like.
I made sure to store the settings used (prompt, model, cfg) in the PNG files.
If you throw one in to the PNG Info tab of Automatic1111 (not sure for other GUIs), you can get the specifics for each image.
