Avoid any plastic, over-smoothed, blurry, waxy skin, flat textures, pixelation, noise, JPEG artifacts, washed-out tones, CGI/cartoon/3D-render look, loss of detail, distorted eyes, or identity changes. Use DPM++ 2M Karras sampler, 50 steps, and CFG scale 7.0 to ensure a photorealistic, raw photography finish that significantly improves clarity and depth while staying faithful to the original image.
