Pencil Sketch Portrait of Woman by Train Window

Create a high-quality, detailed pencil sketch portrait inspired by the composition and mood of the referenced file. The artwork should feature a young woman sitting beside a train window, looking thoughtfully outward at the passing landscape. Her hair should be styled in a loose, messy bun with soft, wispy strands framing her face. She is wearing a textured high-neck ribbed sweater paired with a draped, casual cardigan. The artistic style must mimic traditional charcoal or graphite drawing techniques, emphasizing intricate hatching, shading, and realistic facial features. The background through the window should suggest a motion-blurred view of trees and tracks to convey a sense of travel and introspection, maintaining a moody, cinematic monochrome aesthetic throughout the entire piece.
