In this fantastical birthday greeting card scene, a whimsical yet epic battlefield unfolds, set against a backdrop reminiscent of a vibrant Maxfield Parrish sky with swirling, surreal clouds. In the foreground, a towering birthday cake stands defiantly, its layers adorned with Tyranid spikes and Ork totems, each one humorously painted in bright, clashing colors by mischievous Gretchin. The candles on the cake are designed like Necron gauss flares, glowing with an eerie green light.

To the right, a group of Orks, led by a particularly boisterous Warboss, are enthusiastically engaged in a tug-of-war over a giant banner that reads "Happy Birthday David" in bold, comic letters, reminiscent of Quentin Blake’s style. The banner is hilariously entangled with the limbs of Tyranids, who are more interested in munching on scattered bits of confetti that rain down from above like the ethereal leaves of a Beardsley illustration.

On the left side of the scene, a pair of stoic Necron Warriors, meticulously illustrated with delicate Edward Gorey-esque linework, are attempting to assemble a makeshift throne for David from repurposed Ork scrap metal. In the background, a diminutive, Sendak-inspired Tyranid Ripper cavorts joyfully, clutching a small balloon shaped like a dreadnought.

Above this chaotic yet cheerful melee, the sky is a kaleidoscope of hues where a flock of Norman Rockwell-style cherubic squigs float lazily, each one holding a string of floating letters that spell out "DAVID" across the sky. This birthday tableau captures a humorous clash of iconic Warhammer 40k factions in a celebratory riot of color and detail, perfectly suited for David's special day.

Generated with these themes: Warhammer 40k, Tyranids, Orks, and Necron.
