Create a 3D isometric pastel illustration of a cozy minimalist living room with cool cream walls and a soft lavender or lilac floor. Furnish it with a rounded pastel purple sofa and armchair, minimal cushions, and a light wooden oval coffee table holding two mugs and one pink donut. Include a small side table with a tiny succulent, decorative pastel purple curtains without a window, a wall clock, simple rectangular frame, and metallic lamp. Use soft, cool lighting and a polished, playful style.
