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 while transforming them into an astronaut. Maintain the natural expression and identity of the individual throughout the transformation.

TRANSFORMATION DESCRIPTION:
Transform the person into a professional astronaut standing on the lunar surface. The subject should be wearing a realistic NASA-style spacesuit with a reflective helmet visor. The suit must look authentic with proper detailing including life support systems, control panels, and textured fabric. The helmet visor should reflect the lunar landscape and starry sky. The person's face should be clearly visible through the helmet's faceplate or visor reflection, maintaining their identity.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Photorealistic, cinematic, high-end digital photography
- Lighting: Dramatic lunar sunlight casting long shadows, with soft fill light illuminating the face through the visor
- Color palette: Cool whites and grays of the lunar surface, deep blacks of space, subtle blues and silvers in the suit
- Mood: Majestic, awe-inspiring, professional space exploration
- Background: Detailed lunar surface with craters, rocks, and Earth visible in the distant sky
- Atmosphere: Sharp, clear space environment with stars visible

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face and helmet visor
- Professional quality, cinematic composition
- Aspect ratio: 16:9 (widescreen cinematic) or 4:3 (standard portrait)
- Ultra-detailed textures on spacesuit fabric and lunar terrain
- Realistic space suit materials with proper reflections and lighting

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, poorly rendered spacesuit, cartoonish appearance, low resolution, unnatural lighting, floating objects, anatomical errors, text or logos on suit
