strict realism enhancement no design change enhance the realism of this interior render while keeping absolutely everything unchanged do not modify layout geometry proportions camera angle or perspective materials placement wall colors furniture objects or composition people poses or their positions no redesign no reinterpretation no added elements material enhancement only preserve all existing materials and their exact colors wood enhance wood grain detail and natural variation slightly increase contrast between wood elements floor wall panels furniture while keeping the same color tone and brightness add subtle texture depth and micro imperfections walls keep exact wall color add very subtle gradients and micro texture to avoid flat appearance floor preserve original color and pattern improve realism with soft reflections and slight variation between planks lighting enhance existing lighting only do not add new light sources increase natural daylight coming from the windows create slightly stronger directional light from the right side add soft realistic shadows on the floor especially from furniture and window light improve global illumination and depth add subtle ambient occlusion in corners and under furniture details improve contact shadows under tables chairs and benches slightly enhance contrast and depth in the image keep children s zone and books exactly the same only improve clarity and color definition people keep figures unchanged only slightly integrate them better with light and shadows important if any change would affect design do nothing goal photorealistic enhancement with stronger light direction deeper shadows and more material depth while preserving the exact original design
