Urban Line Atlas Poster

Please generate a high-quality "City Line Drawing Poster". This image is designed based on the visual language of "Monochrome City Line Drawing Travel Poster", including a complete composition: a large title at the top, mid-ground street depth, a central landmark, buildings on both sides, figures in the foreground, and a signature bar at the bottom. [Theme City] City Name:{argument name="city" default="Yichun"} English main title:{argument name="English title" default="FOREST LINE ATLAS / YICHUN CHRONICLE"} Title: Yichun, City of Forests Country/Region: Heilongjiang Province, China Key Landmarks: Lesser Khingan Mountains Forest, Red Pine Forest, Wuying National Forest Park Viewing Tower Street Scene: Streets of a forest town, residential intersections with wooden buildings, forestry city atmosphere Emotional Theme: Commuting in the morning mist Main Color Scheme:{argument name="main color" default="Dark green and dark gray line drawing"} Aspect Ratio: 3:4 Vertical Composition [Overall Positioning] This work serves as a travel souvenir poster, a city visual guide, an architectural line drawing, and an editorial cover design. The image needs to capture the unique character of Yichun as a "Forest City," possessing both urban recognizability and a realistic sense of street life—it's not a standard travel poster or a single landmark illustration, but a visual archive work with collectible value. [Composition Design] The top features a prominent title area using a large English title, "FOREST LINE ATLAS," supplemented by the subtitle "YICHUN CHRONICLE." A numbering system (e.g., No. CN-HLJ-YC-01) and brief coordinate information can be added, creating a modern and design-conscious layout. The central section depicts the main city street scene, employing a deep street perspective composition with a slightly lower angle, showing the road extending into the distance and gradually merging into the forest area. The core landmark is a forest observation tower or the distant forest silhouette, clear yet not obtrusive, naturally integrated into the street scene. Local architectural details are added to both sides: wooden houses, forestry bureau-style buildings, residential areas, small shops, bus stops, streetlights, utility poles, simple road signs, etc., forming a high-density urban information. The foreground includes elements of daily life: pedestrians in autumn and winter clothing, cyclists, residents carrying shopping bags, small vehicles, and fallen leaves on the ground to enhance the seasonal atmosphere. The independent signature area at the bottom is designed as a city archive label structure, containing "YICHUN / HEILONGJIANG / CHINA" and a simplified city information module or map index layout. [Text System] The main title at the top is clear and eye-catching. Only 2-4 clearly readable texts are retained in the image (e.g., "Yichun Station", "Forestry Road", "Bus Stop"), and other signs use abstract Chinese strokes or symbolic characters to avoid garbled text. The overall text system should be unified, restrained, and integrated into the design structure. [Visual Style] The overall style uses monochrome or minimalist two-color line drawings with a beige or warm white paper texture background. The lines are precise, clean, and layered, with the texture of architectural pen sketches and screen printing. The foreground lines are slightly thicker, while the background lines are thinner. The figures and objects are simple yet easily recognizable. The style is restrained and sophisticated. [Innovation Requirements] Incorporate design variations in the following areas: title naming system, top layout structure, a slightly lower-angle street perspective, a composition blending forest and city, a bottom archival information module, and an expression of autumn leaf atmosphere. [Avoidance Guidelines] Reject ordinary travel poster styles, watercolor, thick paint, or cartoon/Q-style styles, cyberpunk, highly saturated colors, and cheap souvenir styles. Please generate a standalone, complete, high-definition, and clearly defined vertical city line drawing poster that possesses collectability and series consistency.
