I need help. I've found that I can't generate realistic skin texture images for certain types of pictures. Some of my images turn out fine—take the examples below: the first is my uploaded image, and the second is the generated one. However, the result is not ideal, and I’m not sure why. All my parameter settings are normal: I selected the Standard model, set Creativity to 0, and chose 4K output. Despite this, some details (like skin texture) just won’t generate properly. Could anyone take a look and help me fix this issue?
