IDENTITY PRESERVATION INSTRUCTION: Using the uploaded photo as the primary reference, preserve the person's exact facial structure, bone structure, eye shape and color, nose shape, lip shape, and unique identifying characteristics. Maintain the fundamental identity while applying natural aging progression.

TRANSFORMATION DESCRIPTION: Age the person forward by 10 years with natural, realistic maturity. Apply subtle to moderate age progression including:
- Natural fine lines and wrinkles (forehead, crow's feet, smile lines)
- Slightly more defined facial features with mature bone structure
- Natural skin texture changes (slight loss of youthful plumpness, more realistic texture)
- Hair style updated to current mature fashion (slightly more sophisticated, professional look)
- Updated clothing style reflecting current trends for someone 10 years older
- Maintain authentic expression but with mature confidence
- Natural lighting that reveals mature skin texture without harshness

STYLE AND AESTHETIC PARAMETERS:
- Photorealistic, cinematic portrait quality
- Natural, soft lighting (golden hour or studio softbox style)
- Warm, sophisticated color palette with professional grading
- High-end photography style (National Geographic portrait, editorial)
- Background: blurred professional studio or modern environment
- Skin texture: realistic pores, subtle imperfections, natural subsurface scattering
- Hair: detailed individual strands, natural volume, slight gray integration if age-appropriate

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face with natural depth of field
- Professional portrait photography quality
- Natural skin texture preserved and enhanced
- Aspect ratio: 3:4 vertical portrait format

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, cartoonish effects, unnatural skin smoothing, excessive wrinkles, sudden drastic changes, identity change, plastic surgery look, exaggerated aging, inconsistent lighting
