INPUT IMAGE (MANDATORY)
Use the uploaded photo as the only identity reference.
Preserve 100% of the subject’s facial features, proportions, skin tone, hair shape, and expression.
Do not beautify or alter facial anatomy.
Strict identity preservation is mandatory (IP-Adapter–level fidelity).
CORE CONCEPT
Transform the subject into a stone pebble mosaic portrait, where the entire image is constructed from smooth, rounded stones of different sizes and colors, carefully arranged to form a realistic and expressive face.
If more than one subject appears in the input photo (e.g., person + pet), all subjects must be included, fully recognizable and emotionally connected.
MOSAIC MATERIAL RULES
The entire image must be made exclusively from:
Smooth pebbles
Rounded stones
River stones
Stones vary in size:
Very small stones for facial details (eyes, nose, lips)
Medium stones for skin and transitions
Larger stones for background and hair flow
No paint, no brush strokes, no illustration textures
Everything must look physically assembled from stones
FACIAL & SUBJECT READABILITY
Despite being made of stones:
Faces must be clearly recognizable
Facial proportions must match the input photo exactly
Eyes must be expressive and well-defined
Lips and mouth must retain softness and realism
If an animal is present, preserve species traits, fur patterns, and expression
COMPOSITION & POSE
Subjects positioned closely, touching or leaning together if present in the reference
Natural, affectionate or calm expression
Frontal or slightly angled portrait
Tight framing focusing on faces and upper body
COLOR PALETTE
Natural stone colors only:
Whites
Beiges
Warm browns
Soft grays
Muted earth tones
No saturated or artificial colors
Smooth color transitions created by stone placement
BACKGROUND
Fully integrated stone mosaic background
No empty space, no flat color background
Background stones should be larger and less detailed than facial stones
LIGHTING
Soft, even lighting
Gentle highlights on stones to show volume and texture
No harsh shadows
Natural, gallery-style illumination
DETAIL & QUALITY
Ultra-high resolution
Extreme micro-detail visible in stone textures
Clean separation between stones

Museum-quality mosaic realism
STRICT NEGATIVE PROMPT
Do NOT change facial identity
Do NOT use paint, illustration, or drawing styles
Do NOT flatten stones into textures
Do NOT distort anatomy
Do NOT add text, logos, or signatures
Do NOT introduce non-stone materials
FINAL INSTRUCTION
The final image must look like the person (and any additional subject, such as a pet) from the uploaded photo has been recreated as a handcrafted stone pebble mosaic artwork, identical in style, density, and realism to the reference image, while remaining unmistakably the same subjects.
