Create a detailed illustration of a birch forest. The scene should depict tall birch trees with their distinctive white bark and black markings, arranged in a dense, serene woodland. The forest floor can include elements like fallen leaves, ferns, small wildflowers, and mushrooms. Add details such as birds perched on branches, a family of deer grazing, and a small stream winding through the forest. The background can feature subtle elements like distant hills or a soft sunlight filtering through the trees. The overall style should be realistic yet tranquil, capturing the peaceful essence of a birch forest. The image should be suitable for coloring, with clear outlines and defined spaces.
