Create a realistic, 3D-rendered image of a landing page focused on UX

Create a realistic, 3D-rendered image of a landing page focused on UX/UI design, featuring floating design elements. The landing page should be displayed on a modern, sleek computer monitor, with various design elements such as buttons, forms, and icons floating around the screen. The elements should have a 3D appearance with realistic lighting and shadows, giving the image depth. The scene should include dynamic lighting, with some elements casting subtle shadows on the background. The overall design should feel modern, professional, and visually engaging, emphasizing a clean and user-friendly interface.
