In this vibrant and humorous hand-drawn birthday scene, the world of Warhammer's Tyranids collides with a heavy metal concert featuring Slipknot. Imagine a bustling concert arena, filled with Tyranids dressed in band t-shirts and holding glow sticks, raising their clawed appendages in a rock-on gesture.

In the foreground, center stage, there is a large, fantastical cake, decked in deep purples and midnight blacks with red piping details, echoing the gothic vibes of the concert. Atop the cake, perched like a gleeful conqueror, is a monstrous Tyranid holding a cake topper that boldly displays the number "13" in fiery orange flames.

Suspended above the crowd, a grand banner unfurls, its tattered edges flapping in the imaginary wind, with bold gothic script that reads "Happy Birthday Travis" in electric blue. The word "Travis" appears again in graffiti-style lettering, scrawled across the side of a speaker on stage, blending into the concert's edgy vibe.

The background is a swirl of activity, with a stylized Slipknot band performing under intense, swirling stage lights of red and white. The band members are abstracted but recognizable with their distinct masks, rendered in a slightly exaggerated, cartoonish fashion.

Surrounding the arena are oversized posters of Machine Head, Lorna Shore, and Amon Amarth, plastered on stone-like walls, their graphics vivid and larger-than-life, each using a palette of moody blues, fiery reds, and metallic silvers to capture the bands' distinctive logos and imagery.

The scene brims with details: an intricate tapestry of coiling wires and instruments litter the stage, and the audience—more Tyranids—are decked out in eclectic costumes, some with oversized headphones, others with band merch, and all illustrated with meticulous attention to their alien anatomy. The concert’s energy is palpable, captured through dynamic, swirling lines reminiscent of Beardsley’s intricate patterns and Blake’s spirited sketches.

The entire composition is unified in a slightly fantastical, yet grounded color palette of deep purples, inky blacks, and vivid metallics, paying homage to the atmospheric storytelling of Rackham and Parrish, while maintaining the humor and whimsy found in Sendak's work.
