### Full prompt
```text
Upscale the reference photo to ultra-high resolution, strictly preserving the subject's identity, facial features, proportions, expression, clothing, and original composition. Sharpen and refine fine details including skin pores and texture, eye clarity, hair strands, fabric weave, and background elements. Maintain the exact original lighting, color grading, shadows, and artistic style with crisp, natural edges and no AI artifacts or distortion.
