创作一幅竖版 3:4 比例的极简马克笔旅行海报，主题为纽约市（NEW YORK CITY），底色为温暖的象牙白纸。

Create a vertical 3:4 minimalist marker-pen travel poster of NEW YORK CITY on warm ivory paper. STYLE: Use a rough, imperfect editorial marker illustration style with a modern folk-art feel. Draw with thick, slightly uneven cobalt-blue contour lines. Apply color with visible felt-tip marker strokes, streaky coverage, pressure variation, dry-skip texture, and patchy density. Do not fill shapes completely. Leave many small and medium uncolored gaps so the warm ivory paper remains visible through clothing, buildings, and street elements. Some outlines should break, skip, or fade. SCENE: Depict two lovers walking closely together on a quiet brownstone street in Manhattan. One gently leans toward the other in a natural affectionate pose. Keep the scene intimate and understated. BACKGROUND SIMPLIFICATION: Include only 4 essential New York cues: one brownstone stoop, one black fire escape, one small corner deli awning, and one faint yellow taxi. Optionally suggest a very faint distant skyline silhouette, but do not add more city elements. Keep the background visually quiet. COMPOSITION: Place the couple slightly below center as the emotional focus. Let the supporting background elements sit loosely behind them with incomplete marker fills and broken contour fragments. At least 40 percent of the page should remain untouched warm ivory paper. Keep the layout airy, elegant, and uncluttered. FINISH GRADIENT: The couple is the most resolved area. Nearby background objects are only about 40 to 60 percent rendered. Distant details and outer edges fade into loose marker strokes and untouched paper before reaching the border. POSTER TYPOGRAPHY: Add the title "NEW YORK CITY" at the top in bold hand-drawn uppercase lettering. Add a small handwritten subtitle such as "summer stroll". COLOR PALETTE: Use a restrained palette of deep cobalt blue, muted slate blue, mustard ochre, warm brown, taxi yellow, and warm ivory paper. Keep the palette limited and slightly muted. MOOD: Romantic, calm, urban, nostalgic, stylish, handmade. NEGATIVE PROMPT: fully filled marker coloring, solid flat fills, smooth vector color, polished digital finish, clean perfect outlines, overly complete rendering, crowded background, too many city elements, dense architecture, detailed signage, realistic textures, glossy surfaces, photorealism, watercolor, oil painting, airbrush shading, 3D render, cinematic lighting, dramatic shadows, cluttered layout, billboard overload, hyper-detailed buildings, perfect symmetry, extra fingers, extra limbs, distorted anatomy, blurry face

创作一幅竖版 3:4 比例的极简马克笔旅行海报，主题为纽约市（NEW YORK CITY），底色为温暖的象牙白纸。 风格： 采用粗犷、不完美的编辑风马克笔插画风格，带有现代民间艺术气息。使用粗细略不均匀的钴蓝色轮廓线勾画。用可见的毡头马克笔笔触、条纹状上色、压力变化、跳墨质感与斑驳密度来上色。不要将形状完全填满。保留许多中小面积未上色的留白，使温暖的象牙白纸底在服饰、建筑与街景元素间透出。部分轮廓线可有断裂、跳笔或渐隐效果。 场景： 描绘一对恋人紧挨着走在曼哈顿一条安静的褐石街道上，其中一人自然温柔地倾向另一人，姿态亲密自然。整体氛围保持亲密而克制。 背景简化： 仅保留 4 个关键的纽约城市意象：一处褐石门廊、一个黑色防火梯、一个小转角熟食店的遮阳棚，以及一辆隐约可见的黄色出租车。可选地暗示一处非常隐约的远处天际线轮廓，但不要添加更多城市元素。保持背景视觉安静。 构图： 将这对情侣置于画面略低于中心的位置，作为情感焦点。背景辅助元素松散地置于他们身后，采用不完整的马克笔上色与断续的轮廓碎片。画面至少 40% 应保留为未着墨的温暖象牙白纸。整体布局保持通透、优雅、不杂乱。 完成度渐变： 情侣是画面中完成度最高的部分。附近的背景物体仅完成约 40% 至 60%。远处的细节与外缘在抵达画面边缘之前，渐变为松散的马克笔笔触与未着墨的纸面。 海报文字： 在顶部以粗体手绘大写字体添加标题“NEW YORK CITY”。再添加一个小型手写副标题，例如“summer stroll”。 配色： 使用克制有限的配色：深钴蓝、柔和的板岩蓝、芥末赭石色、暖棕色、出租车黄与温暖的象牙白纸色。整体色调保持有限且略带柔和感。 氛围： 浪漫、宁静、都市、怀旧、时髦、手作感。 负面提示： fully filled marker coloring, solid flat fills, smooth vector color, polished digital finish, clean perfect outlines, overly complete rendering, crowded background, too many city elements, dense architecture, detailed signage, realistic textures, glossy surfaces, photorealism, watercolor, oil painting, airbrush shading, 3D render, cinematic lighting, dramatic shadows, cluttered layout, billboard overload, hyper-detailed buildings, perfect symmetry, extra fingers, extra limbs, distorted anatomy, blurry face
