Charcoal sketch of a woman on a vintage train

A detailed charcoal sketch style illustration of a young woman sitting by the window inside a vintage train carriage. She has her dark hair tied up in a messy bun with a few loose strands framing her face, and she is wearing a cozy, knitted textured sweater with a high collar. Her arms are crossed comfortably as she looks out the window with a gentle, serene smile. The train window frames a scenic, rolling landscape of hills, trees, and an open sky rendered in expressive pencil strokes and shading. The entire scene captures a nostalgic, peaceful mood with rich monochromatic textures, cross-hatching, and visible pencil line details throughout the interior and exterior elements.
