Retain the principal perspective, the large window on the left, the central rectangular table and chairs, and the low shelves on the right. Replace the cold concrete wall finish with warm light-oak paneling and the floor with natural oak planks; give the chairs comfortable muted rust-colored upholstery. Add subtle warm reading light above the table and a gentle glow along the shelves. Through the existing window, show the soft blue light of dusk. Realistic architectural photography with convincing wood grain, fabric texture and balanced warm interior light against cool outdoor light. The room remains simple, unoccupied and clearly related to the original layout. No text, logos, commercial styling or watermark.",
