Prompt:
A close-up portrait rendered in the style of a Leonardo da Vinci pencil study, where every line is subtle, deliberate and anatomical, built from soft graphite shading, delicate cross-hatching and finely controlled sfumato. The entire illustration is in black, white and graded pencil greys, drawn on sepia-toned parchment paper matching the warm hue of Pantone 465 C — a soft, earthy, antique brown evocative of Renaissance sketchbooks.
The subject is the woman from the reference image, but with distinctly Japanese facial features: refined jawline, high cheekbones, softly slanted eyes, and balanced proportions. Her expression is calm, introspective, with a quiet intensity typical of da Vinci’s portrait studies. Strands of hair are defined with fine pencil strokes, flowing in gentle arcs, rendered with realistic graphite texture and soft shadow gradients.
All is monochrome except for two vivid, striking elements that break the classical atmosphere. She wears modern glasses with thin, elegant frames and slightly reflective lenses. The frames are a vivid metallic violet, shimmering like polished enamel, matching Pantone 2597 C — a brilliant, electric purple with a cool, saturated intensity. The metallic sheen is suggested through controlled highlights and subtle reflections.
Her irises are also colored, creating a surreal, arresting contrast against the monochrome drawing. They are a bright, hyper-vivid emerald green, unnaturally intense, almost glowing — a color inspired by Pantone 802 C, the neon green of high-energy pigments. The pupils remain graphite black, but the irises radiate with impossible saturation, giving the portrait a hypnotic, otherworldly presence.
Everything else — skin texture, shadows, hair, clothing, and background — is rendered exclusively in pencil tones, with soft chiaroscuro and da Vinci-like study marks. The shading emphasizes volume and structure, blending seamlessly into the sepia parchment, as if the drawing were a lost Renaissance sheet infused with two modern shocks of color: metallic violet glasses and neon green eyes.
