Fun fact, MM started from a generated picture where her cutie mark was the only thing I liked, so it's all I saved from that image, and had to inpaint the rest of her around her CM.
here is the image info so you don't have to dig it out of the meta data, if that is even preserved by derpi:
A quick note— I'm pretty sure that that info is just for the last saved inpainting, ie last edit, but the prompt didn't meaningfully change throughout- based on how simple it is that should give you an idea of the MASSIVE amount of editing I did.
