Create a detailed illustration in black and white of various types of seashells scattered on a beach. The scene should include different kinds of shells such as conch shells, scallop shells, and spiral shells, each with intricate patterns and textures. The beach should also feature natural elements like small pebbles, seaweed, and starfish. Include a gentle wave washing up on the shore, creating a natural boundary between the wet and dry sand. Add footprints in the sand leading to the shells and perhaps a distant view of a lighthouse or coastal cliffs in the background. The overall style should be realistic yet serene, capturing the peaceful essence of a beach filled with seashells. The image should be suitable for coloring, with clear outlines and defined spaces. Use only black and white for this illustration. The dimensions should be 8.5 x 11 inches.
