"Create a minimalistic vector illustration with a transparent background, featuring a bold, stylized London landmark (such as a simplified version of Big Ben or the London Eye) or a street artist in action. The design should focus on clean lines, sharp edges, and flat colors—no gradients. Use vibrant, contrasting colors like red, blue, and white to make the design pop. The vector art should have a modern, abstract feel, emphasizing simplicity and clarity. Ensure that the composition is balanced and visually striking. If text is included, use a clean sans-serif font, positioned subtly to complement the design."
