In the foreground of the greeting card, create a detailed hand-drawn scene featuring a superhero version of Robin, but with a playful twist. Robin is depicted as an adult, donning a classic superhero costume with a vibrant red tunic and forest green leggings, complete with a yellow utility belt. He wears a sleek black eye mask and a matching black cape billowing in the wind. His boots are shiny and polished, reflecting the hues of his costume.

Robin holds a whimsical metal detector, stylized to resemble a superhero gadget, in his gloved hand. The metal detector is a bright, eye-catching metallic blue with gold accents, and its display screen lights up with comic-book-style blips and beeps illustrated in dynamic comic book font.

In the background, set the scene in a bustling park teeming with animated details. To the left, a massive, delicious-looking birthday cake towers over a picnic table, iced in pastel blue with cascading rainbow sprinkles. The word "Robin" is cleverly integrated into the icing of the cake, as though piped by a skilled confectioner.

To the right, a group of jovial woodland creatures — a nod to Beatrix Potter's influence — gather around a picnic blanket. These creatures, including a squirrel in a tiny cape, a rabbit with oversized glasses, and a hedgehog sporting a miniature hero mask, are depicted in detailed linework reminiscent of Edward Gorey's expressive style.

The sky above is a wash of vivid sunset colors, from deep purples and oranges fading into lighter pinks, providing a dreamlike Maxfield Parrish-inspired backdrop. In the distance, gently rolling hills are dotted with stylized trees akin to those found in Maurice Sendak’s imaginative landscapes.

Overall, the scene is bustling with intricate details and vivid colors, creating a lively tableau that captures the essence of a birthday celebration with a heroic twist.
