IDENTITY PRESERVATION INSTRUCTION (CRITICAL!)
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 overall appearance and style. The person must remain instantly recognizable as the original subject.

TRANSFORMATION DESCRIPTION
Transform the person into a confident and authoritative business coach or corporate trainer. The subject should be wearing professional business attire such as a tailored suit jacket, blazer, or smart business casual wear (e.g., crisp button-down shirt, elegant sweater). The expression should be approachable yet confident, with a slight smile or focused gaze that conveys expertise and trustworthiness. The overall look should be polished, professional, and ready for corporate presentations or executive profiles.

STYLE AND AESTHETIC PARAMETERS
- Art Style: Photorealistic, professional corporate photography. High-end DSLR camera quality.
- Lighting Conditions: Studio professional lighting with soft key light to highlight facial features, subtle rim light to separate from background, and soft shadows for depth. Natural and flattering light on the face.
- Color Palette: Professional and sophisticated. Neutral tones (charcoal, navy, beige) for clothing, with skin tones kept natural and warm. Background in soft grey, white gradient, or blurred office environment.
- Background Treatment: Clean, professional background. Options: solid soft grey, blurred modern office interior, or subtle abstract gradient. Background should not distract from the subject.
- Composition: Head and shoulders or half-body portrait. Subject centered or using rule of thirds. Direct eye contact with camera.

TECHNICAL QUALITY PARAMETERS
- High resolution, 4K, detailed
- Sharp focus on face and eyes
- Professional quality, corporate photography standard
- Aspect ratio: 1:1 (square) or 4:5 (portrait) recommended for LinkedIn and professional use
- Natural skin texture preserved with minimal retouching
- Clothing should have realistic fabric texture and proper fit

NEGATIVE PROMPT GUIDANCE (what to avoid - technical/quality only)
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, unnatural skin smoothing, artificial-looking clothing, poor fabric texture, mismatched lighting, cartoonish style, low resolution, pixelation, unnatural eye reflections, asymmetrical features, excessive retouching that removes natural skin texture, overly dramatic shadows that obscure facial features, busy or distracting backgrounds.
