Vintage Train Graphite Portrait

Create an ultra-realistic graphite pencil sketch of {argument name="character description" default="a beautiful young South Asian woman"} sitting beside a large window inside a luxurious vintage train carriage, shown from the waist up in a vertical portrait composition. She has a calm, soft expression, slightly smiling, looking out through the window toward the left side of the image rather than at the viewer. Her long, flowing hair is parted near the center and blown gently to the right by wind from the open window, with many fine individual strands rendered in pencil. She wears an elegant embroidered traditional South Asian outfit, a flowing dupatta draped over one shoulder and across her lap, small jhumka earrings, bangles, and delicate floral patterns throughout the fabric. Her hands rest in her lap holding {argument name="held object" default="a small closed book or diary with an oval ornament on the cover"}. The setting is an ornate vintage luxury train interior with polished dark wood paneling, carved trim, a cushioned seat back bearing a decorative monogram emblem, framed wall details, and a small classic wall lamp in the background. Through the window, show a detailed {argument name="outside landscape" default="mountain valley with snow-capped peaks, pine-covered slopes, a winding river, trees, and distant fields"}. Use only monochrome graphite pencil tones on textured off-white paper, with highly realistic facial shading, soft highlights, fine crosshatching, layered pencil gradients, intricate textile embroidery, and atmospheric depth outside the window. The mood should feel romantic, nostalgic, serene, and cinematic. No color, no modern objects, no text, no watermark, no extra people.
