Create a detailed illustration of a woman sitting on the porch of a beachside cabin with a cute spotted cat. The woman should have a serene and content expression, perhaps holding a cup of tea or a book. The cat should be comfortably resting or playing near her, showing a friendly and affectionate demeanor. The porch can include elements like a rocking chair, potted plants, and a view of the ocean with gentle waves in the background. The beach should have natural elements like sand, seashells, and maybe a few distant seagulls. The overall style should be realistic yet tranquil, capturing the peaceful essence of a relaxing moment by the sea. The image should be suitable for coloring, with clear outlines and defined spaces.
