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 professional expert banner portrait. Maintain the natural likeness and individuality of the subject.

TRANSFORMATION DESCRIPTION:

- Color palette: Professional and sophisticated - deep blues, charcoal grays, and crisp whites with warm skin tones
- Background treatment: Modern blurred office environment or abstract professional workspace with bokeh effects, keeping focus on the subject
- Attire: Business professional clothing (blazer, dress shirt, or professional blouse) that appears naturally integrated with the subject's appearance
- Pose: Confident, slightly angled toward camera with natural posture, suitable for banner cropping
- Expression: Professional, approachable, and confident

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, artificial lighting, unnatural skin smoothing, plastic-looking appearance, mismatched clothing textures, background clutter, low resolution, pixelation, unnatural eye reflections, excessive retouching that removes natural skin texture

ADDITIONAL NOTES:

- Background elements should complement but not distract from the subject
- Maintain natural shadows and lighting interaction for photorealism
