Introspective Moment in a Hand-Drawn Graphite Portrait

{
  "prompt": "Ultra-detailed graphite pencil sketch, strict identity lock from reference image, exact facial structure, proportions, skin tone, no alteration. Medium close-up (waist-up), 4:5 aspect ratio. Subject seated at desk, body angled to the right, head tilted slightly upward, looking off-camera thoughtfully. One hand supports the chin, the other hand holds a pencil resting on a sketchbook, natural paused moment. Calm, introspective expression, slightly parted lips, sharp focus on eyes with detailed irises and lashes. Hair styled in a soft messy high bun with loose strands around the face and neck. Clothing: light button-down shirt with rolled sleeves over a darker inner layer, detailed fabric folds. Style: high-end realistic graphite sketch with precise linework, varied line weight, fine hatching and cross-hatching, soft blending for skin tones, visible pencil strokes, realistic hands. Lighting: soft top-left light creating subtle shadows on the right side. Background: clean white paper texture, minimal, sketchbook aesthetic. No color, no digital look, ultra-realistic hand-drawn finish.",
