**Prompt:**

At the top of the illustration image, "Heresy-Level Birthday Wishes, Daniel!"

A humorous, detailed illustration in a cartoon style, featuring a scene set in the grimdark universe of Warhammer 40k. In the center, a Space Marine in full power armor—brightly colored with party patterns and confetti cannons—loudly declares "LET THERE BE CAKE!" while brandishing a massive, absurdly over-the-top chainsword shaped like a birthday candle. Behind him, Orks and Chaos Marines have dropped their weapons in confusion, reluctantly wearing party hats and blowing noisemakers.

To the side, a stoic Tech-Priest awkwardly holds a tray of cupcakes with servo-skulls serving snacks, and a battle-worn Dreadnought is draped in tinsel, trying to pin the tail on the grox. A confused Inquisitor peeks out from a doorway, muttering, "This party may require exterminatus..."

The overall mood is fun and cheeky, blending epic 40k drama with ridiculous birthday celebration elements. Use bright, punchy colors contrasting with classic grimdark Warhammer tones for comedic effect.
