Sketch and line art prompts

Please create a separate, independently designed premium poster from each uploaded photo. Do not combine multiple photos into one composition; output one individual poster for each photo. Use a vertical 3:4 composition, with the upper and lower sections strictly divided 1:1, each occupying exactly 50% of the total height.

Upper Half:  
Preserve the original photograph, maintaining the subject’s identity, structure, pose, realistic texture, natural lighting, and original color atmosphere. Apply only subtle, sophisticated color grading to give it the visual quality of an art magazine, independent publication, or exhibition image. To adapt the image to the 3:4 format, the surrounding background may be naturally extended, but do not stretch, distort, or alter the subject.

Lower Half:  
Extract the most recognizable subject, silhouette, structure, pose, and narrative relationship from the photograph and reconstruct it in the style of Mid-century vernacular graphic illustration + schematic line drawing + two-color spot printing.

Do not completely trace or replicate the photograph. Instead, use diagrammatic abstraction to compress complex objects into a small number of clear geometric shapes, functional contours, and essential structural elements. The result should resemble an illustration from an old instruction manual, advertising card, technical label, or vernacular print: immediately recognizable, yet more direct, humorous, and symbolic than the realistic object itself.

Emphasize economy of line: if a structure can be explained with a single line, do not use unnecessary strokes. Use direct black pen outlines, rectangles, circles, diamonds, straight lines, and simple planes to describe the objects. People, animals, and objects may have slightly exaggerated proportions, while machines, buildings, and complex structures should be simplified into clear boxes, openings, panels, and silhouette relationships.

Use a flat, schematic diagrammatic perspective rather than realistic lighting or strictly accurate spatial depth. The visual language should exist somewhere between illustration and technical diagram, maintaining this distinctive character throughout the composition.

Reorganize the composition according to the most important narrative relationship in the original image. Maintain one clear primary subject, while using a small number of supporting objects, guide lines, directional relationships, or structural symbols to reinforce the story.

Pay close attention to visual hierarchy, geometric order, scale contrast, positive and negative space, and intentional whitespace. The image may feel slightly naïve, awkward, or handmade in a vernacular way, but it must never feel cluttered. Every visual element should appear to exist for the purpose of “explaining what is happening”, rather than simply serving as decoration.

Create a highly detailed “Architectural Passport” travel poster for {argument name="city" default="[CITY / LANDMARK]"}, designed to look like a premium collectible art print that blends colored-pencil illustration, fine ink drawing, vintage architectural documentation, and subtle watercolor texture.

Place the landmark as the dramatic hero, drawn with intricate hand-rendered details, realistic perspective, delicate pencil hatching, visible paper grain, and carefully controlled pops of natural color. Surround it with a faint city map, street names, architectural measurements, tiny elevation sketches, construction lines, botanical details, directional arrows, and miniature diagrammatic studies.

Use an elegant warm ivory paper background with mostly muted graphite, charcoal, terracotta, olive green, dusty blue, and warm beige tones. Keep the background extremely clean and editorial, allowing the landmark to visually emerge from the page.

Add sophisticated typography:
{argument name="city_name" default="[CITY]"}
{argument name="landmark_name" default="[LANDMARK NAME]"}
small coordinates, founding/construction date, architectural style, neighborhood name, and tiny archival annotations.

Include one or two miniature architectural detail drawings beside the main structure, as if taken from an architect’s sketchbook. Add subtle imperfections: pencil smudges, uneven ink pressure, erased construction marks, paper fibers, faint halftone texture, and hand-drawn annotation marks.

The composition should feel like a cross between a vintage travel poster, an architectural magazine cover, a museum exhibition print, and a designer’s sketchbook.

Visual hook: make the landmark extremely detailed and colorful while the surrounding city information remains almost ghost-like, creating a striking contrast between “the place” and “the blueprint of the place.”

Vertical 4:5 composition, premium editorial design, sophisticated negative space, ultra-detailed hand illustration, realistic architectural perspective, tactile paper texture, collectible poster aesthetic, visually striking at thumbnail size, no photorealistic rendering, no 3D CGI look.

画面呈现出一种随性的简笔插画风，一张充满密密麻麻计算的草稿纸占据了大部分画面，计算的字迹凌乱且潦草。在这片凌乱之中，照片中的人以黑色签字笔画出，线条凌乱无序，它似乎迷失在这复杂的计算世界里，像是书写者写累后一时兴起的随手涂鸦。整体画面构图随意，光影上着重突出线条的对比，让图片中人物和草稿纸的凌乱感更加明显
