Craft a joyful, high-contrast black and white line art image capturing the essence of a lively natural landscape. Include detailed, inviting mountains and a playful waterfall cascading with energy. Foreground adorned with cheerful, stylized pine trees and a vibrant lakeshore featuring smooth rocks and a welcoming sandy beach. Populate the scene with friendly animals frolicking near the water and in the forest, adding a sense of life and happiness. Central focus on a gently rippling lake surface, reflecting a serene atmosphere. Opt for a stark, engraving-style line art with bold, clean lines to emphasize the joyful mood, ensuring a symmetrical balance and a filled frame. . --ar 16:9 --s 750
