新选组武士海报

Create a dramatic vertical portrait of a single Japanese samurai, inspired by the late Edo period Shinsengumi aesthetic, standing front-facing in a dark painterly mixed-media composition. The subject is a stern adult male warrior with {argument name="hair style" default="messy black hair tied in a high topknot with loose strands"}, wearing a weathered {argument name="haori color" default="deep indigo blue"} haori over layered black kimono robes and a gray hakama. Add the Shinsengumi-style white mountain-triangle pattern around both sleeve cuffs and a small circular crest on the chest. He carries exactly two swords at his waist: one longer katana angled down to the left with a wrapped handle, and one shorter sword tucked vertically near the center of the obi; his right hand grips near the sword at his side while his left hand hangs tense. Use gritty realistic digital painting with ink splatters, distressed paper texture, dramatic chiaroscuro lighting, and gold-leaf accents. Behind him, place a large pale circular moon or brush-painted disk, with exactly two background scenic elements: a misty Japanese castle on the left and a dark pine tree silhouette on the right. Surround the portrait with bold black brush strokes, scattered ink stains, rough beige parchment, and vertical patches of aged metallic gold. Keep the palette black, charcoal, parchment beige, antique gold, indigo blue, and muted gray. The face may be partly shadowed but should remain a realistic samurai portrait. Add a small elegant signature area in the bottom right containing exactly two text elements: {argument name="date text" default="May 31, 2026"} above {argument name="signature text" default="Oyagi"} in cursive script. Vertical 2:3 poster composition, cinematic, high detail, no modern objects, no extra people, no watermark beyond the requested signature.

创作一张极具戏剧性的竖版单人日本武士肖像，灵感源自江户时代末期新选组的美学风格，人物正面站立，呈现于深色调的绘画混合媒介构图中。主体是一位神情严峻的成年男性武士，留着 {argument name="hair style" default="高发髻束起的凌乱黑发，带有几缕散落的发丝"}，身穿一件褪色的 {argument name="haori color" default="深靛蓝色"} 羽织，内搭黑色层叠和服与灰色袴。在袖口处添加新选组标志性的白色山形纹，胸前饰有小型圆形家纹。腰间佩戴两把刀：一把较长的武士刀刀柄朝左向下倾斜，另一把较短的刀垂直插在腰带中央；右手握在腰侧刀柄附近，左手紧绷下垂。采用粗犷写实的数字绘画风格，融入墨迹飞溅、做旧纸张纹理、戏剧性的明暗对比光影以及金箔装饰。背景处放置一轮巨大的苍白圆月或水墨圆盘，并包含两个背景景观元素：左侧为雾气缭绕的日本城堡，右侧为深色的松树剪影。肖像周围环绕着粗犷的黑色笔触、零星的墨渍、粗糙的米色羊皮纸以及垂直分布的陈旧金属金箔斑块。色调保持为黑色、炭灰色、羊皮纸米色、古金色、靛蓝色和柔和的灰色。面部可部分处于阴影中，但应保持写实的武士肖像风格。在右下角添加一个优雅的小型签名区，包含两个文本元素：{argument name="date text" default="2026 年 5 月 31 日"} 位于 {argument name="signature text" default="Oyagi"} 的草书签名上方。采用 2:3 竖版海报构图，电影级质感，高细节，无现代物品，无额外人物，除要求的签名外无任何水印。
