Since I'm writing the story, I've been using StableDiffusion to help flesh out a few characters and their physical appearance. I have some thoughts and ideas for the characters and how detailed I want them to be.
The images below are just images I generated but not the concepts I am referring to. The concepts I'm referring to will not be generated in this style.
However, as I work more with Stable Diffusion, I'm experimenting and finding new ideas to work with.
When I officially have the concepts I want, I'll use GIMP to edit them to really make the character mine. It's incredible how AI technology can really push a story and help people generate ideas.
