Front and center of the greeting card, imagine a whimsical illustration inspired by a combination of Norman Rockwell's detailed realism and Quentin Blake's lively linework. The scene features a vibrant stretch of Lanzarote's coastline, with a touch of Aubrey Beardsley's intricate patterns swirling in the water.

**Central Image:**

Sarah, depicted with a lively sense of motion, is swimming through the sea in a vintage-style, polka-dotted swimming costume of teal and coral hues, reminiscent of Beatrix Potter's charming color palette. Her swimming hat is a jaunty, contrasting bright yellow, echoing the playful essence of Maurice Sendak's work. The water is a mesmerizing array of aquamarine and azure, its surface rippling with delicate, swirling patterns akin to Arthur Rackham's flowing lines.

**Background:**

The distant shoreline is dotted with rocky outcrops, meticulously detailed like N.C. Wyeth's landscapes, and bathed in Maxfield Parrish's signature twilight blues and purples. A stylized depiction of a swim race leaderboard floats on the surface nearby, where a small banner unfurls, adorned with the text "Sarah" in bold, dynamic lettering.

**Additional Elements:**

In the sky above, Edward Gorey's influence can be seen in a series of playful seagulls, sketched in elegant black and white, contrasting against the warm hues of a setting sun. The horizon is lined with dramatic clouds in Gustave Doré's intricate style, their edges tinged with golden sunlight.

**Details:**

Nestled amongst the rocks, small crabs scuttle in Beatrix Potter-like detail, while a sandcastle in the foreground, reflecting Quentin Blake’s spontaneous energy, proudly flies a tiny flag that matches Sarah's swimming costume. In the corner of the scene, a floating swim trophy sparkles with a touch of Art Nouveau elegance, a nod to Sarah's achievements.

This vibrant, playful scene not only celebrates a birthday but also captures the joy of swimming and the spirit of competition, wrapped in an artistic homage to some of history's most iconic illustrators.
