Ultra realistic cinematic scene. Giant broad-leaf trees on the left and right forming a natural corridor. In the center a very small shallow river, ankle-deep, crystal clear light blue water. Inside and along the river there are pure white stones and leafless white flowers. Extremely detailed, soft natural lighting. Above the center, in the sky, four very large concentric dashed white rings floating. Background is clean flat light beige. Symmetrical composition, wide shot, highly realistic, 8k, cinematic depth of field, calm atmosphere, no people.
