"Create a 3D mockup of a simple, plain white gift bag, designed to look clean and modern. The bag should be centered in the composition, with a focus on its minimalist design. The handles of the gift bag should be subtly detailed, adding to its elegant yet simple appearance. The background should be a soft, solid yellow color, creating a warm, inviting atmosphere while keeping the focus on the product. Use soft, natural lighting to highlight the texture and contours of the bag, ensuring a realistic and high-quality finish. The image should be rendered in super HD, capturing every detail of the bag’s material and shape with perfect clarity. The overall look should be polished and professional, free from any imperfections or distractions. The composition should be minimalist, with no additional elements to draw attention away from the gift bag itself. The subtle shadows and soft reflections should create a sense of depth, while the yellow background provides a cheerful and simple contrast. This mockup should evoke a sense of sophistication, making the gift bag appear ideal for any occasion. The design should be simple yet visually appealing, with a clean and modern aesthetic, showcasing the gift bag in a flawless, realistic presentation."
