Celebratory happy birthday scene, colorful balloons floating in air, bright shining candles on cake, pink and white flowers arranged around, a big golden "Happy Birthday" banner hanging from ceiling, joyful smiling friends gathered around, a sweet lovely girl with curly brown hair, sparkly eyes, wearing a yellow mini dress, holding a cake cutter, surrounded by gifts, confetti falling from above, warm soft lighting, shallow depth of field, vibrant colors, festive atmosphere.
