refine this original v ray architectural render into a more natural photorealistic image with moderate clearly visible improvements in material quality focus on realistic surface details natural wood grain and pores fine fabric weave subtle stone microtextures authentic matte finishes realistic glass reflections and physically accurate material roughness preserve the exact original wood colors flooring pattern ceiling beams decorative wall artwork furniture architecture and all existing materials do not reinterpret or replace any textures or patterns maintain the original lighting direction brightness and soft daylight atmosphere slightly improve light distribution and natural ambient shadows without increasing sunlight intensity contrast or exposure the result should look like a professionally refined version of the same v ray render with more convincing material surfaces but no visible redesign or artificial ai styling no new objects no material substitutions no geometry changes no dramatic sunlight no exaggerated sharpness
