Add a circular downlight effect in the center of the ceiling, casting a soft, focused light pool on the floor. Include LED spotlights for the display shelves, highlighting the products with bright, precise beams. Enhance the scene with realistic textures, shadows, and reflections to emphasize the materials and lighting effects, maintaining the original layout and design.
