Create a square poster that highlights the excitement of travel through a creative fusion of an airplane, bus, and train, each represented in a unique artistic style. The airplane can be illustrated in a surrealistic manner, with whimsical clouds and vibrant colors, while the bus is depicted in a more realistic style, showcasing its details and textures. The train can be represented in an abstract style, with flowing lines and dynamic shapes that suggest speed and movement. Use natural light to create a warm and inviting atmosphere, illuminating each vehicle in a way that enhances its unique characteristics. The background should feature a blend of travel-related imagery, such as maps, compasses, and iconic landmarks, creating a sense of adventure and exploration. Focus on the textures of the vehicles and the expressions of passengers, capturing the joy of travel. Include the text "Discover the World: Travel Beyond Limits" in a bold, eye-catching font that stands out against the vibrant background.
