    "prompt": "> `Final prompt:` A photorealistic image of a white ceramic teacup lying on its side on a wrinkled, light gray fabric background. The teacup is filled with dried yellow flowers, with small clustered blossoms and brittle stems emerging from the rim. The flowers spill out naturally, maintaining an organic arrangement. The lighting is soft and diffused, typical of natural window light on an overcast day, creating subtle shadows and highlights on the fabric and cup. The scene is minimalistic and thoughtfully composed, evoking a calm, rustic atmosphere. The camera angle is slightly overhead with a gentle tilt, capturing the full cup at a diagonal orientation, and showing the handle at the bottom right. The photographic style is moody and still-life inspired, focusing on color contrast between the pale background and the muted yellow blossoms. Rendered in ultra-high resolution, 8k, with fine detail, realistic textures, and soft focus depth."
