16-Expression Character Reference Sheet for YouTube Thumbnails

Create an ultra-photorealistic professional 16-expression character reference sheet using the uploaded character reference image as the ONLY and STRICT source for the character's identity. CHARACTER IDENTITY LOCK: Use the uploaded reference image to preserve the EXACT same character in all 16 portraits. Preserve the exact: facial identity, facial structure, facial proportions, eyes, eyebrows, nose, lips, jawline, cheekbones, chin, ears, skin tone, hairstyle, hairline, age appearance, and distinctive facial characteristics. The same person must appear in every single panel. Do NOT create different people. Do NOT change the face shape. Do NOT alter facial proportions. Do NOT beautify or redesign the character. Do NOT change hairstyle or identity. The ONLY thing that changes between panels is the FACIAL EXPRESSION and corresponding natural hand gesture where specified. ================================================== OVERALL DESIGN ================================================== Recreate the exact visual concept and layout of the provided reference image.

Each individual portrait should have a bright CYAN / SKY-BLUE rectangular background. Create equal spacing between all 16 portraits. Place a clean black text label underneath every portrait. At the very top, centered above the entire grid, add the large bold title: "YOUTUBER THUMBNAILS" Use large heavy black sans-serif typography. ================================================== ROW 1 ================================================== 1 - SURPRISED Character looking extremely surprised.
