You can download any of my images to get the workflow, pretty simple nothing fancy.

Features the character Valby, images for training were not the greatest and will definitely need a v.2 but for now this is what I have. The likeness sticks pretty well but the backgrounds and scenery might not be the greatest. I would lower the strength slightly and really hammer home the style and scenery you want to see.

Using natural language yields the best results, combo it with some tags and avoid things like "1girl" or any other tags that would result is depicting the likeness of another woman.

My training featured describing her and her apparel, so you can very much get her to wear other things. Was trained on my model and I haven't tested it with others, but so long as they're SDXL based I imagine it would be compatible.
