Riverside park in the early morning. Sunlight gently spilling onto the cobblestone path. The back view of a white-haired but spirited elderly man in comfortable sportswear, jogging slowly. Beside him is the shimmering river water. Willow trees on the bank are sprouting tender green branches. The sky is deep blue with a few drifting white clouds. The overall image is bright and clear, with warm and fresh tones, full of positive energy and vitality. Realistic style, rich in detail, high resolution.
