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 image into retro video game style. Keep the core identity recognizable and maintain facial proportions accurately.

TRANSFORMATION DESCRIPTION: Convert the photo into a stylized retro video game character portrait. Apply pixelated aesthetic inspired by 8-bit or 16-bit gaming era (Nintendo SNES, Sega Genesis, Arcade classic). The face should be rendered with visible pixel grid structure, limited color palette typical of vintage consoles, and dithering effects. Include subtle CRT screen scanlines or subtle glow effect for authentic vintage gaming atmosphere. Character should appear as if displayed on an arcade cabinet screen or old CRT monitor.

STYLE AND AESTHETIC PARAMETERS:
- Art Style: Pixel art aesthetic, 16-bit video game style, retro gaming character portrait
- Lighting: CRT screen glow, subtle scanlines, vintage monitor phosphor glow, arcade cabinet lighting
- Color Palette: Limited color palette (16-64 colors typical of retro consoles), vibrant but slightly muted tones, authentic game color restrictions, neon accents
- Texture: Visible pixel grid, dithering patterns, slight chromatic aberration, subtle screen curvature
- Background: Retro game UI elements, pixelated environment, arcade cabinet frame, or solid dark background with game HUD elements
- Mood: Nostalgic, 90s gaming era, arcade atmosphere
- Processing: Subtle pixel smoothing, authentic upscaling artifacts, scanline overlay

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed despite pixelation style
- Sharp focus on face and key features, pixel edges defined
- Professional quality with authentic retro aesthetic
- Aspect ratio: 1:1 (square) for social media avatars, or 4:3 for classic monitor format
- Consistent pixel size and grid alignment
- Clean pixel art rendering without excessive blurring

NEGATIVE PROMPT GUIDANCE: Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, excessive pixelation making face unrecognizable, wrong color palette (modern neon), over-saturated colors, missing pixel structure, modern digital art styles, photorealistic rendering, smooth gradients, vector art, low resolution artifacts, compression artifacts, blurry edges, illegible text, broken UI elements

USER CUSTOMIZATION: {additional_context}
