金銀スチームパンク彫刻ロゴレンダリング

1x1 square ultra-sharp photorealistic render Subject: freestanding steampunk sculpture in the exact silhouette of [BRAND LOGO / LETTER / OBJECT]. packed with interlocking gears, cogs and escapements. Materials: mirror-finish 24-karat yellow gold (#FFD700) plates and gear rims; high-gloss rhodium-plated sterling-silver (#E6E8E9) wheels & bridges; gun-metal screws for subtle contrast. No brass, no bronze, no copper. Color Palette: strictly polished gold & polished silver; zero patina or discoloration. Mechanics: visible clockwork layers: balance wheel, ratchet, mainspring barrel, miniature tourbillon cage; assorted gear sizes (Ø 4 mm–40 mm) meshing realistically; fine screws & rivets. Design: asymmetrically-stacked gear clusters for depth; perforated plates reveal inner workings; no external casing so components float within the letter's contours. Lighting: single soft spotlight above-left (45°) to create warm gold highlights and neutral cool speculars on silver + faint rim-light; crisp micro-shadows under each gear; mirror reflections on polished edges. Camera: front-three-quarter view (yaw ~20°), slight top-down tilt (~10°), tight crop; 85 mm equivalent lens for minimal distortion, f/2.8 bokeh fall-off. Background: seamless matte black velvet, zero noise or texture; no additional props. Render: 8K PBR path-tracing, high glossy roughness variation, perfect anti-aliasing, no chromatic aberration, no vignette. Negative: bronze, brass, copper, aged metal, patina, matte finish, cartoon style, low-poly, plastic look, over-saturated metals, visible text, watermarks, human figures, sci-fi holograms, cluttered background, depth-of-field artifacts.
