Example Results

[kobe bryant]. 
Act as a high-end sports graphic designer creating a conceptual tribute poster. The style is a complex "dual exposure photo-grid composite" with mixed-media textures.
CENTRAL STRUCTURE (THE VESSEL):
The central focus is a large-scale, high-contrast black and white portrait silhouette of [kobe bryant]. This main portrait acts as the container.
THE GRID FILL & TEXTURES (MIXED MEDIA):
The interior of the silhouette is populated by a dense "photo mosaic grid" of action shots from the person's career.
CRITICAL TEXTURE INSTRUCTION: Do not just paste flat photos. Apply artistic textures to various grid cells to create a tactile, collage feel. Use effects like:
Halftone Dots: Comic-book style raster patterns on some cells.
Fabric/Embroidery: Subtle thread or canvas textures suggesting a jersey or patch.
Film Grain: Heavy noise on specific high-contrast action shots.
COLOR STRATEGY:
The base is Monochrome B&W. Use selective color overlays (relevant to the team/flag) ONLY on specific grid cells to create a rhythm.
TYPOGRAPHY & BRANDING (STRICT MICRO-SCALING):
Top Left (The Name): Write "[kobe bryant]" strictly using the font Inter Semibold.
Kerning: Tight negative kerning (-4%).
Size: SMALL and discreet. It must occupy MAXIMUM 20% of the canvas width. Do NOT make it large or loud.
Top Right (The Symbol): Place the primary logo (Team/Brand/Flag).
Size: VERY SMALL. It must occupy MAXIMUM 10% of the canvas width.
COMPOSITION & BACKGROUND:
Background: Off-white or light grey with a visible high-quality paper or concrete texture. It should not be flat digital white.
Alignment: Center the figure perfectly. Maintain wide negative space around the object.
