Create a square poster that captures the essence of travel excitement through a realistic composition featuring an airplane soaring through a bright blue sky, a sleek bus navigating a bustling city street, and a modern train speeding along a scenic route. The artistic style should be realism, showcasing intricate details of each vehicle while incorporating vibrant colors. Use natural light to illuminate the airplane, creating a sense of freedom and adventure, while the bus is bathed in the warm glow of the city, and the train glides through a picturesque landscape. The background should include a lively airport scene, a colorful urban landscape, and rolling hills, all seamlessly integrated. Focus on the textures of the vehicles, such as the shiny metal of the airplane, the smooth surface of the bus, and the sleek design of the train. Enhance the image with subtle post-production effects for depth and clarity. Prominently display the text "Ticket Bazaar" at the top in a bold, modern font, and include the tagline "Your Journey Begins Here!" at the bottom in an inviting style.
