"type": "illustration",
"goal": "创作一幅宽幅电影感插画：一名孤独的牛仔坐在旧西部酒馆门前的木椅上，时值黄昏。画面以精细的手绘墨线勾勒轮廓，并覆盖浓郁的数字上色。技法融合大胆的黑色墨水轮廓线与深邃、多层、完整渲染的色彩表现，呈现出高端杂志插画与图像小说艺术中常见的戏剧性写实风格。",
"work_surface": {
"type": "单幅插画，横向构图",
"aspect_ratio": "16:9 宽屏电影比例",
"medium": "黑色墨水线稿搭配全数字色彩渲染 —— 线稿具有传统手绘墨线的自信笔触质感，色彩则具备受油画影响的数字绘画的深度"

"rendering_technique": {
"line_work": {
"tool_feel": "传统蘸水笔与画笔在纸上的墨水质感 —— 自信、果断的笔触，带有自然的线条粗细变化。不追求矢量般干净，也不追求潦草松散。在精准控制中保留有机的温暖感。",
"outer_contours": "粗黑墨线轮廓（等效3-4pt）清晰勾勒出人物与主要物体。这些轮廓线赋予画面强烈的图形冲击力 —— 即使在缩略图尺寸下，剪影依然清晰可辨。",
"interior_detail": "细墨线（1-2pt）用于面部特征、皮革缝线、木纹、布料褶皱、皱纹、发丝等细节。此类内部细节是高端插画与简单卡通之间的分水岭 —— 对表面纹理与形态的极致关注。",
"spotted_blacks": "战略性使用大块实色墨黑区域 —— 门廊遮檐下的深影、帽檐内部、背心最深的褶皱处。这些黑色块面创造强烈的图形对比，稳定画面构图。",
"hatching": "极少使用。仅在必要处（如门廊天花板底面、深色布料褶皱）出现，为紧密、受控的平行线。绝不松散或装饰性。阴影主要通过色彩而非排线来定义。"

"approach": "在墨线之上进行完整渲染、多层叠加的数字绘画。非平涂，非赛璐珞上色。每个表面都有连续的色调渐变 —— 仿佛每一块区域都以油画习作的精细程度绘制。",
"skin": "多色调表现。暖褐色基底，下颌线与眼窝处带有冷调阴影，鼻部与阳光照射的颧骨略带红润，眉弓与颧骨有精确的高光。皮肤呈现风霜感且富有生命力。",
"materials": "每种材质需区别呈现。皮革在光滑区域有轻微蜡质光泽，在磨损处呈哑光粗糙感。牛仔布可见细微的斜纹肌理。金属（扣具、枪、马刺）具有锐利的镜面高光。木材展现木纹、积尘与岁月包浆。棉质衬衫呈现柔和的漫射透光感。",
"shadow_color": "关键：阴影并非仅是基础色的加深。阴影向冷蓝色-紫色偏移（#2d2d44, #3a3555）。棕色皮背心的阴影不是深棕色，而是带有蓝紫色底调的深棕。这种阴影中的色彩偏移营造出氛围深度与电影般的丰富感。",
"light_color": "夕阳直射处，表面叠加温暖的琥珀金色调（#FFD280, #E8A848）。这是叠加效果 —— 金色光层覆盖在固有色之上，使受光面呈现辉光。"
},
"detail_density": "极高。观者应能放大画面并发现新细节：门廊木板上的单个钉头、皮革上特定的裂纹图案、帽檐褶皱中积尘的方式、威士忌杯口的一处微小缺口、靴底的磨损痕迹。这种对细节的密集观察呈现，营造出一个真实人物所处的真实场景的沉浸感。",

Metal (buckle, gun, spurs) has sharp specular highlights. Wood shows grain pattern, dust accumulation, age patina. Cotton shirt has soft diffused light transmission.",
"shadow_color": "CRITICAL: Shadows are NOT just darker versions of the base color. They shift toward cool blue-violet (#2d2d44, #3a3555). A brown leather vest's shadow is not dark brown — it is dark brown with a blue-purple undertone. This color-shifting in shadows creates atmospheric depth and cinematic richness.",

Sun-weathered skin — deep crow's feet radiating from eye corners, horizontal forehead creases, nasolabial folds that have become permanent grooves. A healed scar across the left cheekbone — thin, white, old. Nose slightly crooked from a long-ago break, a bump on the bridge. Thin lips set in a neutral line — not a frown, not a smile. This face has lived decades of hard outdoor life and it shows in every crease.",

Faded off-white cotton shirt, sleeves rolled to mid-forearm exposing sun-tanned forearms with visible veins and tendons. Dark leather vest over the shirt, well-worn — surface cracked in places, stitching visible at seams, a few spots where the leather has gone matte from years of use. Faded dark blue-grey jeans, lighter at the knees and thighs from wear, dusty. Wide leather belt with an antique brass buckle — the buckle catches one sharp point of sunset light. Holstered revolver on the right hip — dark aged leather holster, the wooden pistol grip visible, a glint of steel. Dark brown leather boots, scuffed and scored, heels slightly worn down, spur straps buckled at the ankle."
