In this delightfully whimsical and photorealistic birthday card cover, the scene is set on an alien planet that exudes the eccentric charm of Doctor Who. The foreground features the iconic TARDIS, its blue police box exterior gleaming under the twin suns. Standing outside the TARDIS is the 4th Doctor, with his unmistakable wild curly hair, broad-brimmed fedora, and that impossibly long multicolored scarf cascading around him. He's holding a colorful paper bag filled with jelly babies, which he is offering to a friendly alien who resembles a cuddly, purple-striped cat with antennae.

In the background, you see a cluster of peculiar yet vibrant alien flora, towering with massive polka-dotted leaves and luminescent blossoms. To the right, a cosmic birthday cake, as tall as the Doctor himself, is whimsically floating mid-air. It's a spectacle of galactic icing, swirled with starry constellations and adorned with a sparking candle shaped like a sonic screwdriver. Written across the side of the cake, in twinkling frosting, is "Happy Birthday Robert" as if the words themselves are gleaming with cosmic energy.

Above, in the sky, whimsical clouds form the shapes of various classic Doctor Who gadgets and symbols, subtly hinting at the sonic screwdriver, a Dalek, and a Cyberman head. Among these playful shapes, the name "Robert" is cleverly incorporated, stretching from cloud to cloud in a playful, cursive script, making it appear as if the universe itself is wishing Robert a happy birthday.
