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 subject into a professional librarian character. The identity must remain 100% recognizable.

TRANSFORMATION DESCRIPTION:
Transform the subject into a sophisticated, intellectual librarian. The person should be wearing classic librarian attire: a structured tweed blazer or cardigan over a modest blouse or button-down shirt. Add stylish, thin-framed reading glasses (round or rectangular) that suit the face shape. The hair should be styled neatly and conservatively, perhaps in a neat bun, ponytail, or professional blowout. The expression should be intelligent, approachable, and focused.

STYLE AND AESTHETIC PARAMETERS:
- Art Style: Photorealistic portrait photography, cinematic quality, highly detailed textures
- Lighting: Warm, soft studio lighting or natural window light from the side, creating gentle shadows that define facial structure. Golden hour warmth to evoke a cozy, studious atmosphere
- Color Palette: Earth tones (browns, tans, creams), warm wood tones, rich book spine colors (burgundy, navy, forest green). Muted, sophisticated colors that convey intellect and tradition
- Background: A blurred library setting with floor-to-ceiling wooden bookshelves filled with vintage books. Depth of field should keep focus sharp on the face while the background remains softly blurred but recognizable as a library
- Attire Details: High-quality fabrics (tweed, wool, cotton), realistic clothing texture, proper fit on the subject's body
- Glasses: Realistic lens reflections, no distortion of facial features behind the lenses
- Makeup: Natural, professional makeup with subtle definition on eyes and lips

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face and eyes
- Professional quality portrait photography
- Aspect ratio: 1:1 (square) or 4:5 (vertical portrait)
- Skin texture: Natural pores and details preserved
- Hair: Individual strands visible, realistic texture
- Clothing: Fabric weave visible, realistic draping

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted features, unrealistic proportions, blurry face, loss of likeness, unnatural glasses placement, cartoonish style, low resolution, pixelation, deformed eyes, asymmetrical face, unnatural skin smoothing, artificial lighting, overexposed highlights, underexposed shadows, text on clothing, logos, modern clothing items, casual wear, sunglasses

ADDITIONAL NOTES:
Ensure the glasses look natural on the face without obscuring key features. The library background should complement the subject without distracting from their identity. Clothing should fit the subject's body type naturally.
