Create a 16:9 pencil-and-charcoal big-head caricature based on the uploaded reference image. Preserve the subject's recognizable identity, overall pose, clothing silhouette, and main expression, but exaggerate the head size and facial proportions for a comic caricature effect, especially the eyes, nose, mouth, eyebrows, and facial contour. Keep a small full-body or upper-body figure beneath the oversized head so the composition reads as one stylized character. Use textured drawing paper, pure black and graphite tones with optional minimal muted accent color from the original outfit, strong pencil brush strokes, charcoal structure, refined linework, expressive shading, soft smudges, and clean negative space. Place the character near the center or slightly above the shoulder area of the composition, with no bottom-right text block. Avoid readable jersey text, team logos, brand marks, creator handles, watermarks, offensive caricature, distorted anatomy, extra limbs, and messy background. Output a high-quality 16:9 image ready for GPT Image 2.
