Create a detailed illustration of a vast lavender field in full bloom. The scene should depict rows of lavender plants stretching into the distance, creating a sense of depth and perspective. Include a few natural elements like butterflies, bees, and perhaps a small farmhouse or windmill in the background. The sky should be clear with minimal clouds, focusing on the vibrant lavender fields as the central element. The overall style should be realistic yet tranquil, capturing the peaceful essence of a lavender field. The image should be suitable for coloring, with clear outlines and defined spaces.
