Geometric Line Art Architecture Poster

Create a high-resolution 3:4 poster based on the city. The poster uses a 1:1 split layout. The top half is a realistic scene capturing the core atmosphere of the theme (cityscape, street life, culture). The bottom half extracts the subject's structure and silhouette, reconstructing it as a minimalist geometric line art graphic with thin lines, clear perspective, and restrained negative space. Includes an integrated typography system for titles, coordinates, and years. Colors should be custom-tailored to the theme's specific mood rather than using generic templates. The final result should be clear, modern, and aesthetically sophisticated. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
