Lionel Messi is wearing the official Argentina national football team jersey (outfit). His expression is calm, confident, and introspective, conveying leadership, humility, and greatness. On the table, positioned to his left, stands a highly detailed LEGO-built replica of the FIFA World Cup trophy, constructed from golden LEGO bricks with realistic proportions and subtle green accents. The official LEGO logo is clearly visible on the base of the trophy or subtly placed in the foreground. Lionel Messi delicately holds in his right hand a LEGO minifigure representing himself, wearing the official Argentina national team uniform, including authentic sky-blue and white colors, number 10, captain’s armband, and facial features inspired by his real likeness. The FIFA World Cup 2026 logo is subtly integrated into the background or softly embedded into the table surface, appearing slightly out of focus to enhance depth. The image is ultra high-definition, with sharp focus on Messi and the foreground elements, complemented by a cinematic depth of field that creates a smooth, artistic background blur.

FAQ
- Why does the prompt require exactly one reference image?
- The rules enforce a single primary_subject upload with 0.995 identity lock strength to guarantee the generated face matches the reference without any morphing or drift.
- How can I adapt this for a different social platform?
- Keep the 4:5 ratio for Instagram but change the creative_prompt scene_summary to a daytime version with window light if targeting Stories or Reels thumbnails.
