This model is not about a hyperrealistic look. Instead, it aims to have imperfections in the picture with slightly off proportions to make it look somewhere between a sketch on the way to the actual painting without adding the small details. The model is trained on simplified digital pictures, and character portrays. It can be used for text-to-text or image-to-image to get the style and look of old-school RPG character pictures like you would find in the PC games of the 1990s and early 2000s or today in some of the independent game titles.
It’s also a good starting point if you need a picture as a basis to then draw yourself more details over it. Said something that can integrate into the creative process as an intermediate way of creating unique artwork.
