Front and center, a whimsical yet intricately detailed scene unfolds, capturing the unique and unexpected fusion of Warhammer Tyranids in a lively concert atmosphere. The alien-like Tyranids, with their chitinous exoskeletons and multi-limbed forms, are packed together in a chaotic crowd, their expressions and poses showcasing an odd excitement as they watch Slipknot perform on stage. Slipknot members are vividly depicted, with their signature masks and dynamic postures, as they rock out under a flurry of colorful stage lights. The lights splash vivid shades of purples, reds, and blues across the scene, casting the Tyranids in a mesmerizing glow.

Behind the audience, tall posters plaster the background wall, each boldly displaying artwork for Machine Head, Lorna Shore, and Amon Amarth. The posters are richly illustrated, featuring the bands’ logos and iconic imagery in a blend of gothic and metal styles.

To the left of the scene, a colossal birthday cake towers over the concertgoers. Its surface is elaborately frosted in dark shades of violet and black, topped with a striking "13" sculpted from crimson sugar. The cake is adorned with small, colorful figurines that echo the Tyranid theme, some peeking out from layers of frosting, others clinging to its sides.

Above the cake, a large, arching banner unfurls with ornate calligraphy, stating "Happy Birthday Travis." The letters are playfully integrated with illustrations of swirling tendrils and creeping vines, reminiscent of both gothic and Art Nouveau influences. Just below the banner, in the sky, the name "Travis" is subtly woven into a cloud formation, blending seamlessly yet distinctly, with the suggestion of rock band aesthetics.

The background is a concert venue, with dark curtains hanging along the sides and a stage with amplifiers and drum kits detailed with band logos. Overhead, spotlights add a dramatic flair, cutting through artificial fog that lingers above the crowd. The floor is littered with confetti and empty soda cups, giving a sense of a wild and ongoing celebration.

This cover marries the fantastical elements of the Tyranids with the high-energy metal concert vibe, creating an unexpected and visually rich birthday greeting card scene for Travis.
