Magnificent model, as I said. After testing I have opted for my own model of positive and negative prompt, I like it best.
Better than reality itself, and an amazing level of detail without too many steps. If someone downloads the photo, they can zoom in the Windows photo viewer, and the details look realistic even from very very close. I was impressed by the detail of the iris, the texture of the skin. With the same prompt no one has reached such realism and detail.
10/10, I hope you keep improving the model (if you can improve something so good).
I've used DPM++ 2M Karras with 30 steps, Hires fix upscale x 2, steps on 0 and the Upscaler 4x-UltraSharp in the first photo. On the other two only DPM++ 2M Karras at 50 steps, no hires fix, changing the positive prompt a bit to get the sunlight directly on the face.
