The scene is set on a rocky alien planet under a star-studded galaxy with nebulas swirling in vibrant hues of deep purples, blues, and radiant pinks, inspired by Maxfield Parrish's luminous colors. In the background, immense gothic spires rise, resembling the intricate architectural style reminiscent of Gustave Doré's cathedrals. They loom tall and ominous, intricately detailed with gothic arches and statues.

In the foreground, a birthday celebration unfolds with Warhammer 40k and dark fantasy themes. At the center, the Emperor of Humanity stands with majestic grandeur. His armor is a masterpiece of art, painted in metallic gold and regal blues, adorned with baroque flourishes and ornate decorations akin to Arthur Rackham’s detailed illustrations. His expression is fierce and commanding, his eyes focused forward as he raises an elaborate goblet crafted with intricate engravings.

Beside him stands a Space Marine, clad in a colossal suit of power armor. The armor is dark, almost black with midnight blue highlights, showing off immense bulk and complexity, designed with rivets and battle scars that speak of countless wars, a nod to the heroic illustrations of N.C. Wyeth. His helmet is adorned with a crest of feathers that flutter in the space breeze, adding an element of dynamic movement.

Scattered around them are fantastical creatures drawn in an expressive, whimsical style, reminiscent of Maurice Sendak and Quentin Blake. There’s a tiny, impish demon clutching a gift, its wrapping paper a collage of shimmering golds and reds. A delicate faerie hovers nearby, her wings iridescent, fluttering over the scene like a guardian, while small, dragon-like creatures peer curiously from behind rocks.

The centerpiece is an enormous, decadent birthday cake, designed in a style that could only be dreamed by Edward Gorey. Its layers are gothic and twisted, with a rich, dark chocolate hue topped with an explosion of vibrant, colorful frosting. On top of the cake, in shimmering gold icing, the name "JEREM" is proudly emblazoned, drawing the eye as if it were a celestial banner.

Above all, a cosmic sky stretches infinitely, dotted with stars and planets, pulling the viewer into the grandeur of the universe. The whole illustration is alive with detailed, expressive lines that capture the awe-inspiring mix of Warhammer 40k’s epic scale with the mystical allure of dark fantasy, all blended into a humorous and extravagant birthday card.

Generated with these themes: Warhammer 40k, Dark fantasy, The emperor of humanity badass, and Space marine badass.
