Create a modern aesthetic moodboard that captures the essence of urban landscapes through a vibrant digital collage. The composition should feature bold and vibrant colors, such as electric blues, fiery oranges, and vivid greens, to evoke an energetic atmosphere. Incorporate geometric shapes like triangles, circles, and lines that intersect with photographic elements of cityscapes, skyscrapers, and street art. The moodboard should reflect a dynamic interplay between the geometric forms and the urban environment, appealing to creative professionals seeking inspiration. This artwork should serve as a visual representation of modern urban life, perfect for design presentations or creative brainstorming sessions.
