田园少女油画肖像

创作一幅竖构图的古典油画肖像，描绘 {argument name="character name" default="一位年轻农家少女"}，采用 19 世纪欧洲现实主义风格。画面为胸部以上特写，人物居中，面朝前方，神情安静而严肃，皮肤白皙透亮，双颊微红，蓝灰色双眸，五官精致，双唇微启，额前露出几缕浅金色发丝。她戴着一条宽大、松散包裹的 {argument name="headscarf color" default="灰粉色"} 亚麻头巾，头巾带有层叠的褶皱、磨损的边缘，布料垂在脸颊两侧；身穿一件破旧的 {argument name="clothing color" default="暗橄榄棕色"} 乡村风格衬衫或夹克，缝线处有裂纹，笔触粗犷。背景是柔和的乡村田野，有起伏的农田、远处的树林、左侧一座红屋顶的小农舍、地平线上的低矮丘陵以及多云的金色天空。采用来自左上方的自然暖光，使用厚涂法笔触，色调以大地绿、赭石色、灰褐色和柔和粉色为主，面部细节细腻，背景笔触则更为松散。构图呈现出古典大师田园肖像画的质感，亲切而忧郁，左下角带有红色草书艺术家签名。画面中无现代物品，除签名外无任何文字，避免摄影感。

Create a vertical classical oil painting portrait of {argument name="character name" default="a young peasant girl"} in a 19th-century European realist style. She is shown from the chest up, centered and facing forward with a quiet, serious expression, pale luminous skin, subtle rosy cheeks, blue-gray eyes, delicate features, slightly parted lips, and a few wisps of light blonde hair visible at the forehead. She wears a large, loosely wrapped {argument name="headscarf color" default="dusty pale pink"} linen headscarf with layered folds, frayed edges, and trailing fabric down both sides of her face, plus a worn {argument name="clothing color" default="muted olive-brown"} rustic blouse or jacket with cracked seams and rough brush texture. The background is a softly painted rural countryside with rolling fields, distant tree lines, a small farmhouse with a reddish roof on the left, low hills on the horizon, and a cloudy golden-gray sky. Use warm natural light from the upper left, painterly impasto brushstrokes, earthy greens, ochres, taupes, and muted pinks, with fine detail in the face and looser brushwork in the landscape. Composition should feel like an old master pastoral portrait, intimate and melancholic, with a small red cursive artist signature in the bottom-left corner. No modern objects, no text except the signature, no photography look.
