Create a vibrant birthday-themed background featuring a colorful balloon arch that stretches across the top, with pastel-colored balloons in shades of pink, blue, yellow, and green. Below the arch, scatter a variety of festive decorations, including shimmering confetti, a large, multi-tiered birthday cake adorned with candles and colorful sprinkles, and wrapped gift boxes of different sizes. In the corners, place happy birthday banners strung between playful party hats and oversized cupcakes, with a sunny blue sky and fluffy white clouds in the background to convey a joyful celebration atmosphere.
