Behind it, showcase proud landmarks that are inspired by the architecture of an old British city, under a brilliant cascade of fireworks illuminating the evening sky. Integrate colorful birthday elements like party hats and a banner reading '21st' into the scene, blending harmoniously to evoke a sense of festivity. This scene should radiate an authentic, personalized touch corresponding to a city-inspired celebration.
