At the top of the Cartoon Style image, “Happy 24th birthday Justin”

Funny, playful Cartoon Style with exaggerated proportions, thick black outlines, and bright saturated colors. Scene: A triumphant truce birthday bash between Warhammer-style Space Marines and Chaos Marines in a grand gothic sci‑fi hangar. Center stage: a towering multi‑tier cake on a hazard‑stripe table, confetti blasting, balloons bobbing, sparklers blazing, and big “2” and “4” number candles. On the left, heroic blue-and-gold Space Marines in chunky power armor, purity-seal stickers fluttering; on the right, spiky, horned Chaos Marines in brassy reds and blacks, one cheeky tentacle piping pink frosting onto the cake. Everyone looks very cool and over-the-top: swaggering, energetic poses, dynamic low-angle, cinematic smoke and rim-lighting. LOTS of oversized sci‑fi guns everywhere—bolt‑style rifles, chain-swords, plasma pistols—comically dressed with streamers, party hats on muzzles, and gift wrapping. A servo-skull with a tiny party hat delivers a cupcake; a melta is used like a candle-lighter; tanks in the back are draped with colorful bunting; a starfield glows through a viewport. Color palette: candy brights (electric blues, hot pinks, acid greens, sunny yellows); bold cel‑shading; glossy highlights. Keep it humorous, energetic, and non-violent—no gore, no logos.

At the bottom center, a small playful ribbon reads: “Ceasefire for cake!”
