The old nautical charts and vintage decorative borders create a timeless aesthetic, while the silhouette of the submarine and marine life illustrations hint at the book's underwater setting. The choice of deep blues, browns, and golds as primary colors further enhances the theme. The typography selection complements the overall design, with a bold serif font for the title conveying a sense of adventure, and an elegant script font for the author name adding a touch of sophistication. The use of a thick, textured paper stock adds to the tactile experience, inviting readers to engage with the book.
