"prompt": "A photorealistic still life scene featuring a large bundle of fully bloomed, soft yellow-orange English garden roses with lush, layered petals arranged in a clear cylindrical glass vase filled with water. The vase is placed on a slightly wrinkled black cloth-covered table. A human hand with medium skin tone is gently grasping a glossy ceramic yellow cup beside the vase. The background consists of a moody, dimly lit wall with subtle texture and cracks, partially cast in shadow, creating a softly dramatic atmosphere. The lighting is natural and low-key, coming from the left side, casting gentle highlights and shadows across the flowers and vase. The person in the frame is dressed in a black top and is mostly cropped out of the image. Dark, modern aesthetic with warm and muted tones, shallow depth of field. Shot from a close-up, eye-level angle. Style is cinematic and atmospheric, in 8k ultra high-resolution, photorealistic, unreal engine rendering quality."
