Transform the uploaded portrait into a highly detailed black-and-white graphite pencil caricature while preserving the person's identity. Keep the same hairstyle, facial features, earrings, necklace, turtleneck sweater, and coat. Use subtle facial exaggeration inspired by professional caricature art (slightly larger eyes, slightly elongated face, fuller lips, refined nose) without making it look unrealistic. Render with intricate pencil strokes, cross-hatching, soft shading, and hand-drawn sketch textures on a clean white background. Place the original color portrait as a small rectangular reference image on the left side and the finished graphite caricature as a much larger drawing on the right, matching the composition of the reference image. Remove any watermark, text, logo, or signature. Ultra-detailed, museum-quality pencil illustration, crisp linework, realistic graphite textures, elegant artistic finish, 8K.
