复古火车石墨肖像

创作一幅超写实的石墨铅笔素描，描绘 {argument name="character description" default="一位美丽的南亚年轻女性"} 坐在豪华复古火车车厢内的大窗户旁，采用竖构图，展示腰部以上的部分。她表情平静柔和，面带微笑，望向画面左侧的窗外，而非注视观众。她留着一头长发，中分的发丝被开着的窗户吹进的风轻轻向右拂动，铅笔勾勒出许多细腻的发丝。她身着优雅的南亚传统刺绣服饰，肩上和膝上披着飘逸的纱巾（dupatta），佩戴着小巧的耳环（jhumka）、手镯，织物上布满了精致的花卉图案。她的双手放在膝上，拿着 {argument name="held object" default="一本封面带有椭圆形装饰的小型闭合书籍或日记本"}。背景是装饰华丽的复古豪华火车内饰，配有抛光的深色木镶板、雕花装饰、带有装饰性字母组合标志的软垫座椅靠背、框架墙壁细节以及背景中的小型古典壁灯。透过窗户，展示出细致的 {argument name="outside landscape" default="带有雪山顶、松树覆盖的山坡、蜿蜒河流、树木和远方田野的山谷"}。仅使用单色石墨铅笔色调，绘制在有纹理的米白色纸张上，强调高度逼真的面部阴影、柔和的高光、细腻的交叉排线、分层的铅笔渐变、复杂的纺织品刺绣以及窗外的大气深度。整体氛围应充满浪漫、怀旧、宁静和电影感。无色彩，无现代物品，无文字，无水印，无其他人物。

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.
