This workflow generates a new facial expression using Flux2.Klein, then refines it with an SDXL model. In the end, you get the full image, and an image of only the face. This could be useful for game creation.

I've been thinking about this project for a while, but I've been busy with other things. Initially, I wanted to do it exclusively in SDXL, but I got tired of struggling with just SDXL.
