Such as eye color, railroad tracks, an interesting pose, high contrast, etc. A lower cfg score allows the AI to follow your prompt a bit less and decide what to do itself. I usually use something in the 7-12 range (most often 9 or 10).

Since I've gotten some messages about this... The denoising score for hires fix determines how much of your image will change. Usually 0.5-0.7 is usually a good place to start. 1.0 changes the image completely - steps are better for adding detail than using 1.0. #stablediffusion
Finally, cfg scale is how closely your prompt is followed. In my case, I have 1girl in my prompt - my intent was not 2 pictures of girls on top of each other, 1 girl with 2 faces, etc and as cfg scale increases that's enforced more as well as other things.... (1/?)
