NightCafe still doesn't like to generate centaurs!
This image (originally a horse and rider) was first imported from another AI art program. I used 'Stable Inpainting' about 30 times to change it into a centaur. Too much work!
It was the most difficult task so far. I didn't submit anything. I forgot to interrupt the challenge series with this... Yours turned out to be a good picture! :)
