use the existing rendering as the strict base image the current design materials and composition are already correct do not change the flooring in any way do not replace redesign recolor or reinterpret the existing floor the only task is to improve the realism and cleanliness of the existing rendering material and surface quality make all existing materials look highly realistic clean and professionally rendered improve realistic material textures natural surface variation realistic roughness realistic reflections realistic light interaction subtle shadows natural material depth physically believable surfaces clean and consistent shading remove any visible blotchy areas cloudy patches artificial color variations rendering artifacts texture noise grain dirty looking surfaces uneven shading low resolution texture appearance unnatural transitions between materials large surfaces should appear smooth calm and homogeneous while still retaining subtle realistic material characteristics wood should have believable natural grain and variation painted surfaces should be clean and even textiles should have realistic subtle fabric texture stone metal glass and other hard materials should have physically believable roughness and reflections important do not make the materials overly glossy overly perfect or artificial do not add fake patina or unnecessary texture the result should look like a high quality professional architectural photograph not an ai generated image lighting improve the realism and consistency of the existing lighting use soft natural daylight realistic light falloff natural shadows subtle indirect light believable reflections balanced exposure avoid overexposed areas crushed dark areas excessive contrast artificial hdr appearance cold or sterile lighting dramatic cinematic lighting preserve everything else do not change architecture geometry room proportions camera perspective composition furniture furniture positions fireplace doors windows wall colors flooring materials decorative objects plants rug do not add anything do not remove anything do not redesign anything the goal is simply existing rendering cleaner surfaces more realistic materials more natural lighting higher photorealism nothing else should change
