Create a serene autumn park scene with a tree full of golden-yellow leaves in the center. Surround the tree with a lush garden of vibrant purple and white flowers, mixed with green foliage. In the background, show a wide, grassy meadow fading gently into a soft blur. Use warm, soft lighting typical of an early autumn afternoon, casting a golden glow over the entire scene. Capture fine details in the plants and leaves, with vivid colors that emphasize the transition of the seasons. The atmosphere should feel peaceful and dreamlike, with a slight depth of field effect. --ar 5:4
