I want this picture, taken in 8K ultra high definition realistic photography, with a 1:1 square composition. In the upper left corner of the picture, there is a sun emitting soft white light, and the clear and transparent blue sky is clean and pure. The foreground is a large green lawn with a wide field of vision. The texture of the lawn is delicate and realistic, with natural light and shadow. In the center of the lawn stands a huge ancient tree with a thick trunk and lush branches. The tree crown is stretched and dense, the leaf layers are distinct, and the color is bright. The tree casts clear and soft shadows on the lawn. The overall picture is fresh, bright, and healing, with full details and no AI distortion --v 8.1
