Vector image marine-themed postcard with sea stars, shells, nautiluses, wave, and text space on blue watercolor

On a delicate watercolor background reminiscent of soft ocean waves, an exquisite composition of snow-white marine creatures is arranged. Ethereal sea stars of various shapes — from classic five-pointed ones to whimsically curved forms — harmoniously coexist with ornate shells and spiral-shaped nautiluses. Each element is drawn with astonishing detail — visible are the finest lines on the surface of the shells, the textured patterns of the sea stars, and the spiral curls of the nautiluses. A wave-like contour framing the composition on the left adds a special dynamism, creating the sensation of ocean surf. The watercolor background transitions from light turquoise to nearly white, mimicking the play of light in the depth of water. The airiness and weightlessness of the drawing are achieved through the white color of the marine elements, which seem to float in a blue haze. This work is ideal for designing invitations to a seaside party, creating cards for summer greetings, designing menus for coastal restaurants, decorating photo albums with marine memories, or crafting decorative panels for interiors in a nautical style.
