Joyful Disney-style Treasure Discovery Portrait for Smartphone

Create a vibrant and joyful scene in portrait orientation for a smartphone, where a character, in the style of Disney animation, is being celebrated for discovering a hidden treasure. The character should have an expression of excitement and pride, holding a glowing treasure chest filled with gold and jewels. Surrounding the character, there are magical sparkles and confetti falling from the sky, with a background that features a lush, enchanted forest or a mystical cave filled with shimmering lights. The colors should be bright and uplifting, with a soft, dreamy atmosphere typical of Disney classics.
