创作一张纵向 3:4 的极简马克笔旅行海报，主题为 NEW YORK CITY，底色为温暖的象牙白纸张。

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

创作一张纵向 3:4 的极简马克笔旅行海报，主题为 NEW YORK CITY，底色为温暖的象牙白纸张。 风格： 采用粗粝、不完美的编辑插画式马克笔风格，带有现代民间艺术气息。用粗厚、略带不均匀的钴蓝色轮廓线勾画。以可见的毡头马克笔笔触上色，呈现条纹状覆盖、压力变化、干笔飞白质感与斑驳密度。不要将形状完全填满。保留许多小到中等大小的未着色间隙，使温暖的象牙白纸面在衣物、建筑与街道元素之间可见。部分轮廓线应出现断裂、跳跃或淡化的效果。 场景： 描绘一对恋人亲密地走在曼哈顿一条安静的赤褐色砂石街道上。其中一人自然温柔地倚向另一人，保持亲密、含蓄的姿态。 背景简化： 仅包含 4 个关键的纽约元素：一个赤褐色砂石门廊、一个黑色防火梯、一个小街角熟食店雨棚、一辆隐约可见的黄色出租车。可选择性地暗示一抹非常微弱的远景天际线轮廓，但不添加更多城市元素。保持背景在视觉上的安静。 构图： 将恋人置于略低于画面中心的位置，作为情感焦点。让背景支撑元素松散地置于他们后方，配以不完整的马克笔填色与断续的轮廓碎片。画面中至少 40% 应保持未被触及的温暖象牙白纸面。整体布局保持通透、雅致、不拥挤。 完成度渐变： 恋人是画面中完成度最高的区域。邻近的背景物体仅完成约 40% 到 60%。远景细节与外边缘在接近边框前逐渐过渡为松散的马克笔笔触与未着色的纸面。 海报字体： 在顶部添加标题 "NEW YORK CITY"，采用粗体手绘大写字母。下方添加一个小号手写副标题，例如 "summer stroll"。 色彩搭配： 使用克制的配色，包括深钴蓝、柔和的板岩蓝、芥末赭黄、暖棕色、出租车黄与温暖的象牙白纸张。配色保持有限且略带柔和。 氛围： 浪漫、平静、都市、怀旧、时髦、手工质感。 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
