Prompt

Prompt

Create a minimalist architectural line-drawing rendering in a clean competition-style illustration. Render the building using thin, precise black or dark-gray linework only, with no color fills, no textures, and no photorealistic shading. Clearly express façade grids, structural rhythm, and floor articulation through consistent line weights. Use subtle line layering to indicate depth between foreground, midground, and background buildings. Depict the sky using horizontal hatch lines to create a calm atmospheric backdrop. Draw trees, landscape, and ground surfaces with lighter, softer outlines so they remain secondary to the architecture. Add minimal human figures and birds as simple contour silhouettes for scale. Keep the overall composition clean, balanced, and quiet, with a white background and a refined architectural drawing aesthetic suitable for competitions or academic presentations.
