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 them into a Twilight-style vampire character. Maintain the original identity and likeness throughout the transformation.

TRANSFORMATION DESCRIPTION: Transform the subject into a supernatural vampire character from the Twilight saga universe. Apply the signature Twilight aesthetic: extremely pale, translucent skin with a marble-like quality, subtle veins visible beneath the skin, and eyes that glow with a golden or red hue (depending on preference). The transformation should make the person look like a centuries-old immortal being with an ethereal, timeless beauty. Add the characteristic mysterious and brooding expression associated with Twilight vampires.

STYLE AND AESTHETIC PARAMETERS:
- Art Style: Cinematic photorealism with a dark, moody atmosphere. High-end fantasy photography style.
- Lighting Conditions: Dramatic, moody lighting with strong contrast. Soft, diffused light from the side to create depth and shadow. The "Twilight" blue-hour lighting (cool, desaturated tones) with hints of golden warmth in the eyes.
- Color Palette: Cool, desaturated colors dominated by blues, grays, and silvers. Skin should appear extremely pale, almost white with a slight blue undertone. Eyes should have a supernatural glow (golden amber for Cullen family style, or deep red for tracker style). Background should be dark and atmospheric.
- Background Treatment: Dark, misty forest background or a moody indoor setting with shadows. Background should be slightly blurred (bokeh effect) to keep focus on the face. Can be a Pacific Northwest forest atmosphere or a gothic interior.
- Texture: Skin should have a smooth, marble-like texture. Hair should be styled in a sleek, natural manner. Clothing should be modern but elegant (dark sweater or fitted shirt).

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face
- Professional quality cinematic portrait
- Aspect ratio: 2:3 vertical portrait format
- Ultra-detailed skin texture with realistic pores and subtle imperfections
- Cinematic depth of field

NEGATIVE PROMPT GUIDANCE: Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, unnatural skin texture, cartoonish appearance, over-saturated colors, bright daylight lighting, cheerful expressions, modern clothing logos, text or watermarks, low resolution, pixelation, unnatural eye glow, plastic-looking skin.
