Brutalist Concrete 3D Typography Design Prompt for Leonardo

Design a monumental brutalist typography composition rendered as massive 3D concrete letterforms. The word or phrase should be sculpted from raw, poured gray concrete with visible formwork texture, wooden plank imprints, aggregate speckles, and subtle hairline cracks that convey weight and permanence. Each letter emerges from a solid architectural slab, casting deep hard-edged shadows under dramatic directional lighting. Use an oversized, ultra-bold condensed sans-serif typeface inspired by mid-century brutalist architecture — think thick strokes, blunt terminals, and heavy geometric proportions. Place the letterforms within a minimalist environment: an empty concrete plaza or a matte charcoal studio backdrop with soft atmospheric haze. The lighting should be a single strong key light from the upper left at a low angle, creating long cinematic shadows and sculpting the rough surface relief, complemented by cool ambient fill to reveal texture in the shadows. Color palette restrained to cement gray, ash, bone white, and deep slate, with one optional accent of weathered rust-orange or oxidized teal staining the concrete for contrast. Emphasize tactile realism: moisture stains, efflorescence, chipped edges, exposed rebar hints, and a fine matte microtexture across every surface. Compose with strong negative space, centered or rule-of-thirds placement, and a slightly low camera angle to amplify scale and intimidation. Render in photorealistic quality with crisp focus, physically accurate materials, and subtle depth-of-field falloff in the background. Aspect ratio 4:5 or 1:1 for poster use, high dynamic range, 8K detail. Negative prompt: glossy plastic, cartoon, blurry text, warped letters, cluttered background, oversaturation, low resolution, soft mushy edges.
