Features & Hair: Large almond-shaped eyes with detailed irises and catchlights, softly arched dark eyebrows, slim straight nose, full softly shaded lips, smooth oval face, and a graceful neck. Hairstyle: [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].

Shoulders and lower bust lightly sketched, fading into the plain white background. Fashion illustration aesthetic. Strictly monochrome, no color, no background objects, no text, no watermark.
