Create a travel banner with a minimalist design using generative AI techniques. The image should showcase a traveler's suitcase placed against a clean and calm background. Leave enough empty space for text, enabling easy customization for different travel-related ideas. Ensure the image is of high resolution and top-quality, with clear and detailed renderings of all elements, including the suitcase's texture and the smoothness of the background. The aspect ratio should be 16:7, and the image should have a width of 750 pixels. The style should be raw.
