Retrato expresivo de mujer en estilo de lápiz suave

Create a portrait of a woman with an emotive, expressive face, rendered in beautiful, detailed line-work reminiscent of classic masterpieces (e.g., Leonardo da Vinci or Rembrandt). The image should have a subtle, dreamy quality, achieved through soft shading and a muted color palette. The background should be softly blurred, with a stylized aesthetic that evokes a delicate, handmade sketch. Use fine, flowing lines to capture her emotions, with a focus on her eyes and mouth. The overall composition should feel intimate and timeless, as if drawn with charcoal or pencil on textured paper.
