Create a vibrant and exciting Fortnite-themed birthday card for a 12-year-old boy named Maximilien. The scene should capture the dynamic and colorful world of Fortnite, featuring a lush landscape with iconic elements such as battle buses, supply drops, and popular Fortnite characters in action poses and real estate agents. The background should include a mix of natural and urban environments typical of the game, with a bright and cheerful atmosphere. Important: The text "BON ANNIVERSAIRE" should be prominently displayed in a fun and playful font, integrated seamlessly into the scene. Ensure the text stands out and is clearly readable. The overall design should be energetic and visually appealing to a young Fortnite enthusiast, making Maximilien feel excited and special on his birthday.
