Design a 300 DPI coloring book page that captures the essence of a serene wilderness. Picture a tranquil forest glade. In the foreground, a graceful deer sips water from a clear pond, its reflection almost perfect. Surround the pond with lush ferns, blooming wildflowers, and tall, ancient trees whose branches are home to perched songbirds ready to greet the day. Further back, hint at the depth of the forest with more trees, perhaps a squirrel or two, and a distant owl returning from its hunt. Use only clear black outlines to depict this scene, ensuring ample white spaces within and between elements for artists to fill with their choice of colors. Remember, no shading; let the outlines and spaces inspire the artist's imagination.
