IDENTITY PRESERVATION INSTRUCTION:
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while generating a completely new background that complements their appearance and style. The person's likeness must remain 100% intact and recognizable.

TRANSFORMATION DESCRIPTION:
Create a detailed, immersive background that matches the character's visual identity, clothing style, and expression. The background should feel like a natural extension of the person's story. For example: if the person is wearing futuristic clothing, generate a cyberpunk cityscape; if wearing fantasy attire, create a mystical forest or castle interior; if in casual wear, place them in a cozy café or urban street. The subject should blend seamlessly into the scene with realistic lighting integration and proper shadows.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Cinematic photorealism with high detail, matching the quality of professional character portraits
- Lighting: Dynamic lighting that matches the background scene (e.g., neon glow for cyberpunk, golden hour for outdoor scenes, soft ambient for interiors). Ensure the subject is lit consistently with the environment
- Color palette: Harmonious color scheme that complements both the subject's clothing and the background atmosphere. Colors should flow naturally from subject to environment
- Background treatment: Fully rendered environment with appropriate depth of field. Background should be rich in detail but not distract from the subject. Include atmospheric elements like fog, particles, or light rays if appropriate to the scene
- Integration: Seamless compositing with realistic edge blending, matching skin tones to ambient lighting, and proper shadow casting onto the background surface

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face with appropriate background bokeh
- Professional quality character portrait
- Aspect ratio: 3:4 vertical portrait or 16:9 cinematic (user can specify)
- Ultra-detailed textures on both subject and background
- Consistent depth and perspective

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, mismatched lighting between subject and background, unnatural edge blending, floating subject effect, background artifacts on the subject, inconsistent color grading, low resolution, cartoonish appearance, plastic skin texture

USER CUSTOMIZATION:
{additional_context}

ADDITIONAL TIPS:
- For best results, ensure the original photo has good lighting and clear facial features
- You can specify background preferences in the additional_context field (e.g., "cyberpunk city at night", "fantasy castle interior", "cozy library", "futuristic spaceship bridge")
- Mention specific mood or atmosphere you want (e.g., "dramatic", "peaceful", "mysterious", "epic")
- If you want specific color schemes, describe them in additional_context
- For character roles: specify if you want the person to look like a specific character type (warrior, mage, detective, etc.)
