Black and White Pencil Portrait

Create an ultra-detailed black-and-white pencil line-art portrait of {argument name="character description" default="a young woman with delicate symmetrical features"} on a clean white paper background. Show a front-facing bust portrait cropped from the shoulders upward, with the head slightly turned but eyes looking directly at the viewer. The expression is calm and gentle with a faint closed-mouth smile. Render large almond-shaped eyes with detailed irises and catchlights, softly arched dark eyebrows, a slim straight nose, full softly shaded lips, smooth oval face, and a long graceful neck. Style the hair as {argument name="hairstyle" default="dark medium-length hair parted in the center, loosely swept back into a soft messy updo with wispy strands framing both sides of the face"}. Use meticulous graphite pencil technique: fine layered linework, realistic cross-hatching, subtle tonal gradients, visible individual hair strokes, delicate skin shading, and crisp facial detail while keeping the shoulders and lower bust lightly sketched and fading into the white background. Maintain a realistic yet idealized fashion-illustration look, high contrast in the hair, soft shading on the face, no color, no background objects, no text, no watermark.
