Create a whimsical birthday illustration in which a parade of vibrant classic vehicles are decked out with radiant balloons and festive flags. In the heart of the scene, an antiquated convertible shines under the celebratory lights, bearing a massive birthday cake topped with whimsical candles. In the back, confetti falls gently upon a group of diverse, smiling individuals in party hats. They all cheerfully celebrate against a softly sketched backdrop of city landmarks, under a sky that's lit up by twinkling stars.
