gushi,spring,A towering biyu-green willow tree reaching up into the clouds, its feicui-green branches drooping like silk ribbons. A close-up of the willow leaves shows thousands of tender green branches swaying gently in the breeze. Next to the willow tree flows a small river, with flowers in full bloom along the riverbank. Morning mist swirls around the trunk, while sunlight filters through the leaves, creating dappled light spots on the ground. (3D cartoon modeling, Pixar animation quality, ultra-fine leaf texture) The scene is rendered in a highly detailed and realistic cartoon style, with each leaf showing intricate vein patterns and a slightly translucent appearance. The overall atmosphere is serene and dreamy, with soft lighting and vibrant yet natural colors enhancing the beauty of nature.
