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 applying neon lighting effects. Maintain the original facial structure, expression, and identity with 100% accuracy. The person should remain instantly recognizable.

TRANSFORMATION DESCRIPTION:
Transform the portrait with vibrant neon lighting effects. Add customizable neon glow around the subject's face and shoulders. The neon light should create dramatic rim lighting, subtle face contour highlights, or full atmospheric glow. Choose from neon colors: electric cyan, hot magenta, deep violet, or electric blue. The glow should look like real neon light casting on skin, creating realistic reflections and color bleeding on facial features without obscuring identity.

STYLE AND AESTHETIC PARAMETERS:
- Style: Photorealistic cinematic portrait with cyberpunk/neon aesthetic
- Lighting: Dramatic neon rim lighting, soft glow on skin, realistic light falloff
- Color Palette: High contrast between natural skin tones and vibrant neon accents
- Mood: Futuristic, edgy, mysterious, high-tech
- Background: Dark environment (deep black, dark gray, or blurred city night) to make neon pop
- Texture: Realistic skin texture preserved, individual hair strands visible, natural pores
- Neon Effect: Should integrate naturally with facial contours, creating realistic highlights and shadows

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)
- Cinematic color grading with HDR quality
- Ray-traced lighting effects for realistic glow

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, overexposed neon washing out features, neon colors bleeding into eyes in unnatural way, plastic-looking skin, unnatural glow edges, mismatched lighting direction, cartoonish effects, low resolution, pixelation, facial asymmetry, identity change
