IDENTITY PRESERVATION INSTRUCTION: Using the uploaded photo as the primary reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics. Maintain the original facial structure, proportions, and identifiable traits while applying the natural portrait transformation.

TRANSFORMATION DESCRIPTION: Create a professional portrait with a natural, authentic aesthetic. Apply subtle, minimal makeup that enhances natural features rather than covering them. Use soft, diffused lighting that flatters the face without harsh shadows. The overall look should be clean, fresh, and approachable - capturing genuine personality with a polished yet natural appearance.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Photorealistic portrait photography with natural skin texture
- Lighting: Soft, diffused natural window light or studio softbox lighting with gentle fill
- Color palette: Natural, warm-neutral tones; skin should look healthy and luminous
- Background: Clean, blurred background (bokeh) in neutral tones or subtle gradient
- Makeup: Minimal and natural-looking - enhanced brows, subtle eye definition, natural lip color

- Expression: Genuine, warm, professional smile or neutral confident expression
- Detail: Individual eyelashes, natural hair texture, realistic skin tones
