IDENTITY PRESERVATION INSTRUCTION (CRITICAL!)
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 entire image into a mosaic art piece. The face must remain instantly recognizable despite the artistic transformation.

TRANSFORMATION DESCRIPTION
Transform the uploaded photo into a beautiful mosaic artwork composed of thousands of individual tiles that form the complete portrait. The mosaic should be created from small, uniform tiles in various colors that accurately represent the original image's shading, gradients, and details. The person's face should be the focal point of the mosaic, with the tiles arranged to create depth, texture, and dimension while maintaining facial structure and likeness. The mosaic effect should cover the entire image including background, but the facial features should be clearly defined through strategic color placement in the tiles.

STYLE AND AESTHETIC PARAMETERS
- Art style: Classical mosaic art with a modern digital twist, photorealistic tile rendering
- Tile appearance: Small rectangular or square tiles with subtle grout lines between them
- Lighting: Natural light simulation with highlights and shadows created through tile color variation
- Color palette: Rich, vibrant colors derived from original photo with slight artistic enhancement
- Texture: Textured tile surface with slight gloss or matte finish depending on user preference
- Background: Integrated into the mosaic pattern, not separate from the effect
- Mood: Artistic, elegant, timeless, gallery-worthy
- Tile density: High density for detailed facial features, slightly larger tiles in less critical areas

TECHNICAL QUALITY PARAMETERS
- High resolution, 4K, detailed mosaic tiles
- Sharp focus maintained on facial features despite tile transformation
- Professional quality, gallery art standard
- Aspect ratio: 1:1 for classic mosaic presentation (adjustable to 4:3 or 16:9 based on user preference)
- Individual tile edges should be crisp and well-defined
- Color transitions between tiles should be smooth and natural
- No pixelation or blurring in the mosaic pattern

NEGATIVE PROMPT GUIDANCE
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, pixelated appearance, mismatched tile colors, unnatural color banding, excessive tile size variation, face becoming unrecognizable, low resolution tiles, muddy color transitions, artifacts in tile rendering

ADDITIONAL TIPS FOR BEST RESULTS:
- For a more classical look, request warmer earth tones in the tiles
- For a modern look, request cooler tones and sharper tile edges
- Specify if you want the mosaic to include a frame or border
- Mention preferred tile size (small for detailed, larger for abstract)
- Indicate if you want the background to be part of the mosaic or a solid color
