I like this game, and while there are some pony models for a couple of characters, there wasn't one of Momori, so here you go.
Early version. There are Pony XL and Illustrious XL versions, trained with 21 images. Using just the standalone keyword is sometimes enough, but using more specific descriptions yields better results.
