refine the existing render while strictly maintaining the original geometry composition camera angle and overall design intent lighting soften and diffuse the lighting throughout the space reduce harsh highlights and bright hotspots especially near the window and central courtyard create a more even ambient illumination with gentle gradients and balanced exposure maintain a warm tone but avoid overly orange or blown out areas couch material enhance the existing couch material to read clearly as fabric introduce subtle fabric texture soft grain and slight variation in light absorption keep the same color form and proportions do not change the design only improve material realism wood material refine all wood surfaces to appear more natural and cohesive reduce streakiness and overly sharp grain contrast ensure the wood grain flows consistently in the correct directional orientation along each surface maintain the same tone and color but make the finish more even smooth and realistic overall improve material realism and cohesion while preserving the minimal warm and calm atmosphere of the space do not add or remove objects and do not alter any forms or layout
