Hand-Drawn Linear Sketch Art

Generate a paper-based line drawing visual work based on a specific theme. The image is first established by extremely fine, slightly shaky hand-drawn lines to build space, subject outline, structural transitions, paths, and scale relationships. Then, a few high-purity color surfaces are introduced only to the most critical recognition planes, connection nodes, emotional pauses, and centers of gravity; color is not a full fill but acts as precise annotations to edit attention. The overall visual area is dominated by warm off-white paper and black fine lines. Paper texture, tiny spots, and a slight scan feel should be clearly present. Ample white space is reserved above or around to make the subject appear as if observed in a page of a travel manuscript. Visual weight is concentrated in the middle or lower-middle part, maintaining breathable distance around the subject. The composition consists of a clear anchor, a low-density environment layer, and a few colored nodes. The core object maintains recognizable structural lines, outlines, local hatching, and compressed details. Details gather along edges, openings, corners, and movement paths. Volume and shadows are achieved through fine hatching and varying line density. Background appears as a low-density line-art memory layer. Added tiny figures or symbols serve as scale 'noise' to give a sense of life and usage. If text is needed, use narrow, restrained annotation-style fonts. The final surface shows the finish of pen line drawing, colored pencil, or light ink overlay, with quiet, open, manual textures and slight perspective errors.

Prompt original

围绕具体主题内容生成一张纸本线描视觉作品，画面先由极细、略带手绘抖动的线条建立空间、主体轮廓、结构转折、路径和尺度关系，再让少数高纯度色面只进入最关键的识别平面、连接节点、情绪停顿和信息重心；色彩不是完整上色，而是像精确批注一样编辑注意力。整体以温暖米白纸场和黑色细线为最大视觉面积，纸纹、微小斑点和轻微扫描感要清晰存在，上方或外围保留充足空白，让主体像被放进一页旅行手稿中被观察。主要视觉重量收束在画面中部或中下部，主体周围保持可呼吸的纸面距离，构图由一个清晰锚点、低密度环境层和少量彩色节点组成。核心对象保持可识别的结构线、轮廓边缘、局部排线和压缩细节，先把主题拆成边缘、平面、路径、节点、尺度标记和语义环境，再决定哪些部位允许被色彩激活；非关键区域交给纸色和线稿，不做平均填色。细节沿结构边缘、开口、转角、连接处和运动路径聚集，开放区域保持纸面放空，线条方向服从对象语义，流动处用稳定平行线场，暗部用竖向或交叉排线，脆弱边缘用短促断线。体积、阴影和材质通过细排线、交叉线、平行线场和线密度变化完成，线条压在色面之上，色块边缘带轻微手工错位和纸纹渗透感。背景由主题自身的空间或信息环境生成，但只能作为低密度线稿记忆层出现，用轻轮廓、远近关系、稀疏标记和少量排线说明地点、时间、尺度或语义压力，背景比主体更轻、更少色、更低对比。色彩保持受控的冷暖角色分工：纸色与黑线压住全局，少量冷结构色建立空间和秩序，少量暖记忆色点亮入口、转折和情绪，最亮色只作为稀疏小节点停顿；当主题改变时，色相跟随主题语义微调，但面积层级、饱和集中、冷暖分工和点状高光必须稳定。画面中加入极小的人物、器物、符号或功能标记作为尺度噪点，用几笔线和点状色彩表现，使空间产生使用痕迹和生活温度，这些标记应小到只改变节奏而不成为主角。若需要文字，使用细窄、克制、低干扰的注记式字形，像建筑草图边注一样参与边界、路径 and 信息层级，保持留白完整。最终表面呈现钢笔线描、彩色铅笔或薄墨套色、细线压色、轻微套色偏差、纸纤维、扫描颗粒和手绘透视误差的完成度，既有准确结构，又有安静、开放、带现场记忆的手工质感。本次主题：人民大会堂特写 比例1:2 用途： 手机壁纸
