The scene is a fantastical birthday celebration set in an otherworldly realm where the organic and the mechanical intertwine. In the foreground, there's a large, intricately detailed birthday cake in the shape of a Tyranid creature, with chitinous plates made of dark chocolate and bioluminescent icing that glows a vivid electric blue, like Lorna Shore's album covers. Atop the cake, the number "13" is crafted from metallic spikes resembling Slipknot's iconic masks, painted in a reflective gunmetal gray.

Surrounding the cake, several Warhammer Tyranid figures stand as if in a concert mosh pit. These creatures are intricately illustrated with sinewy limbs and serrated exoskeletons, painted in a mix of bone white and deep purple hues, akin to the color palettes favored by Gustave Doré. Their eyes glow with an eerie neon green.

In the background, an immense banner hangs suspended between two jagged cliffs. The banner is made from a patchwork of concert flyers and album covers from Machine Head and Slipknot, with a weathered, vintage look that pays homage to Edward Gorey. Bold, graffiti-style letters spell out "Travis" across the banner in blood red.

Above, the sky swirls with abstract cloud formations reminiscent of Maxfield Parrish's work, painted in shades of twilight violet and midnight blue. Among the clouds, ethereal, translucent figures inspired by Aubrey Beardsley's line work dance to an unheard metal symphony.

Around the edges of the scene, delicate pen-and-ink illustrations echo Quentin Blake's lively strokes, depicting guitars with strings of silver and drums that resemble giant, ornate beetles from a Maurice Sendak story.

This birthday scene is a fusion of surreal fantasy, detailed craftsmanship, and thematic elements that tie together the love for Warhammer Tyranids and metal music, all brought to life with a rich tapestry of colors and meticulous artistry.
