Im glad you liked it, I prepared a drive folder with the background images here Drive with Images
I hope it does not change your perspective but I did not make the images 100% by me (well actually I make them, but also used AI to get the texture and colors),
The process was the following:
I took a cat photo from the internet and draw some line art on krita (pincel ink 8px) with plain base colors, then I use AI to refine and give it that "crayon drawing" texture. I will post a devlog with the details on how I get it
That's a wonderful way to use AI and you saved time from hours of drawing and avoided the 'AI Slop' look!
