A city skyline at sunset with floating orange and white spheres, creating an abstract pattern. The buildings should be detailed and realistic against the backdrop of a gradient sky from light grey to dark navy blue. A few small red or black sphere shapes can add depth. Use soft lighting to cast gentle shadows on the ground, enhancing reflections in the water below. This artwork is designed for wall art decoration, combining modern architecture elements with artistic expression in the style of modern abstract art. --ar 3:5
