Generate a dynamic and festive image capturing a vibrant New Year's Eve celebration. The main subject should be elegantly dressed in sophisticated party attire, such as a glittering sequined gown or a sharp, celebratory tuxedo. The background should feature a spectacular display of colorful, bursting fireworks illuminating the night sky, symbolizing the stroke of midnight. Abundant metallic confetti in various colors should be actively falling and scattered throughout the scene, creating a sense of joy and movement. The overall atmosphere should convey the exhilarating energy of a 'midnight countdown', with celebratory expressions, dramatic lighting, and a sense of effervescent anticipation.
