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 transforming the image into a stylized profile icon. Ensure the likeness remains 100% accurate, maintaining natural facial proportions and recognizable details such as mole, scar, or distinctive eye shape.

TRANSFORMATION DESCRIPTION:
Transform the photo into a professional profile icon suitable for a specific brand or theme. The icon should feature a centered, square composition with the face as the focal point. Apply a cohesive visual style that matches the target brand or theme-e.g., corporate clean (sharp suit, neutral tones), creative vibrant (bold colors, artistic elements), or tech minimalist (futuristic, sleek). The transformation should integrate subtle thematic elements (like color accents, minimalistic background patterns, or stylized framing) without distorting the person's appearance. The result must look like a high-end digital avatar or professional headshot optimized for social media or business use.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Photorealistic with a polished, commercial finish; slightly stylized to match the brand theme (e.g., corporate professional, modern creative, or sleek tech). Avoid heavy artistic filters; keep it clean and recognizable.
- Lighting conditions: Studio-quality soft lighting or natural light simulation to highlight facial features evenly. Use subtle rim lighting or a soft glow to add depth without harsh shadows. Ensure the face is well-lit and inviting.
- Color palette and mood: Align with the brand/theme-e.g., for corporate: muted grays, blues, and whites for a trustworthy, professional mood; for creative: vibrant pops of color (e.g., teal, magenta) for an energetic, modern vibe. Maintain the person's natural skin tones; no unnatural color shifts on the face.
- Background treatment: Clean, non-distracting background-either a solid color matching the theme (e.g., light gray for business, gradient for tech) or a subtle blurred environment that doesn't compete with the face. Keep the background simple to emphasize the icon's focus.

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed output with sharp edges and crisp details.
- Sharp focus on face: The eyes and facial features must be in perfect focus, with no blurring.
- Professional quality: Suitable for print or digital use; no artifacts, noise, or compression issues.
- Aspect ratio: Square (1:1) for optimal profile icon use; ensure the face is centered and occupies 60-70% of the frame height.
- Additional specs: Smooth skin texture, natural hair details, and balanced contrast. Use high-fidelity rendering to mimic a professional camera shot.

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, over-stylized effects that obscure identity, mismatched lighting on face, unnatural skin tones, low resolution, pixelation, or any elements that make the image look amateurish or unprofessional. Do not include any text, logos, or watermarks in the image.

USER CUSTOMIZATION:
{additional_context} (e.g., specify the brand colors, theme description like 'tech startup vibe' or 'corporate executive', preferred background color, or any specific accessories like glasses or jewelry to include.)

ADDITIONAL TIPS FOR BEST RESULTS:
- Upload a clear, front-facing photo with good lighting for optimal transformation.
- If the theme involves specific colors, mention them in the customization section for precise application.
- Test with multiple generations if needed to fine-tune the brand integration while preserving likeness.
