The base image from this is one of the images from thisfursonadoesnotexist.com, basically the only one I can find that was not a dog, wolf, fox, or Judy from Zootopia. I guess we know who was over-represented in the initial set. Also, a character from Undertale? Draw your own conclusions.

Anyways, I popped the original image into Disco Diffusion, and after a ton of trial and error, landed on "A cute mouse fursona with big ears, long brown hair with auburn highlights, tan fur, and vibrant turquoise eyes, wearing a soft cloth grey tshirt" as solid base input. Ran it a few times, merged the images with masked layers in Photoshop (the best tool), manually fixed a couple of areas that were misshapen, and then ran it through again.

There were a few areas that had a hard time generating under the full prompt. The hair, for instance, is mostly just from the prompt "long brown hair with auburn highlights." The hair draped on her shoulders came from that. Most of those added details are from Disco Diffusion, not my editing. The freckles, the more realistic ear details, that sorta thing. Interestingly enough, I couldn't get it to manually add good whiskers no matter how much I tried, even when giving it white lines to work off of.

There's a site https://thisxdoesnotexist.com/ with all sorts of things from images to text to html, etc. I figured it'd be fun enhance AI images with more AI, and the furry one had the best candidates. I'm not a furry, but I couldn't resist using this base image, because she's absolutely adorable. Don't judge me.
