"Design a 3D mockup featuring a sleek smartphone with a plain white screen, tilted slightly but still facing forward. The device should be the central focus of the composition, showcasing clean lines and smooth edges to convey a modern and premium aesthetic. The background should be a warm gradient of yellow to orange, with a subtle, thin texture to add depth and visual interest without overpowering the main subject. Lighting should be perfectly balanced, highlighting the contours and reflective surfaces of the smartphone while ensuring there are no harsh glares or dark shadows. Use soft, even illumination to enhance the overall composition and bring out the realistic details of the phone’s design. The image should be rendered in super HD for flawless clarity, capturing every detail with precision. Keep the design minimalist, free of additional elements or clutter, to maintain a clean, professional look. The background and phone should harmonize, creating a visually appealing and sophisticated presentation. Every detail must be impeccable, with no distortions, blemishes, or imperfections, ensuring a polished and high-quality final result. This mockup is ideal for emphasizing the phone’s design and adaptability while presenting it in a vibrant, modern setting."
