### Full prompt
```text
Medium & Style: High-contrast monochrome grayscale [graphite sketch] combined with a subtle realistic skin tint, blending academic portraiture with dynamic fashion illustration.
Linework & Structure: Clean yet energetic hand-drawn pencil strokes with visible construction lines, loose geometric guidelines, overlapping angular sketch marks, and intentionally unfinished raw edges. Strong line-weight variation and crisp facial features.
Shading & Texture: Soft graphite blending, delicate cross-hatching, feathered shading, and layered tonal rendering on warm off-white drawing paper with natural paper grain and visible graphite texture.
Color Accent: Realistic skin with a gentle, natural [peach-beige] tint, echoing warm sun-kissed lighting, while the rest of the artwork remains strictly grayscale graphite.
Hair & Background: Hair rendered with sculptural, faceted pencil shapes, sharp planes, and flowing sketch lines. Minimal background featuring faint perspective guides and an abstract geometric framework.
Lighting: High-contrast directional lighting with deep graphite shadows and bright paper highlights, replicating a dramatic shadow cutting across the face.
Aesthetic: Traditional sketchbook aesthetic, elegant, raw, artistic, highly detailed concept art.
