Vector image postcard with a marine theme featuring sea stars shells nautiluses wave and a text area on blue watercolor

Smooth transitions of watercolor washes create a sense of marine depth, where airy blue tones flow into one another, forming a dreamy space. Against this ethereal background, white silhouettes of sea creatures and shells are elegantly arranged — starfish of various shapes and sizes, graceful nautilus shells with their characteristic spiral structure, and wavy outlines of seashells. A special dynamism is added by an elegant white wave, curved in a flowing line, as if frozen in the moment of its movement. Each marine element is drawn with meticulous attention to detail — the textural features of the starfish surfaces, the spiral patterns of the shells, and the finest lines shaping volume and texture are all visible. The artistic technique combines the watercolor blur of the background with sharp, graphic contours of the marine treasures, lending the work an airiness and, at the same time, a sense of structure. The empty space on the left is deliberately left for the potential placement of text, making the image functional for designing invitations, postcards, covers, or promotional materials with a marine theme. This illustration is perfectly suited for decorating wedding invitations in a marine style, summer greeting cards, menus for coastal restaurants, and labels for cosmetics with marine ingredients.
