Design a cityscape at sunset featuring a modern, sleek skyscraper with an abstract design, surrounded by a variety of futuristic buildings. In the foreground, include a luxury yacht with a streamlined silhouette, slightly altered colors, and without any recognizable branding. The water should reflect the golden hues of the sunset while maintaining a tranquil atmosphere. Ensure the skyline captures a mix of architectural styles, giving a sense of urban sophistication and elegance.
