The birthday greeting card's front cover is a surreal and intricately detailed scene that combines the vibrant intensity of "Attack on Titan" with the whimsy of a birthday celebration.

**Central Figure: Eren Yeager**

Eren Yeager is depicted with meticulous detail, standing confidently at the card's center. He's drawn with a fusion of Aubrey Beardsley's detailed linework and the imaginative style of Maurice Sendak. Eren is dressed in his classic Scout Regiment uniform, with the iconic green cloak billowing around him. In his hands, he holds a birthday cake that's elaborately decorated. The cake features multiple tiers, each layer adorned with intricate patterns reminiscent of Gustave Doré's style. The top of the cake has small, detailed figures of Titans, intricately crafted in a similar vein to Arthur Rackham's creatures.

**Background Elements:**

The background merges the fantastical elements of Maxfield Parrish and the dynamic storytelling of N.C. Wyeth. The setting is a lush, surreal landscape, with towering, intricately drawn trees that echo the grandeur of Beatrix Potter's nature scenes. These trees have exaggerated, swirling branches, reminiscent of Edward Gorey's gothic whimsy.

In the sky, vivid, swirling clouds rendered in Maxfield Parrish's signature, vibrant colors dominate. The sky transitions from deep blues and purples at the top to golden yellows and soft pinks closer to the horizon. Nestled among these clouds are airships and elements from the "Attack on Titan" universe, rendered in Quentin Blake's playful, dynamic line style.

**Foreground Details:**

Scattered across the foreground are delicate, detailed flowers and whimsical creatures peeking out from behind the foliage, taking inspiration from Arthur Rackham's storytelling style. These elements are filled with subtle, muted colors, enhancing the vibrant scene without overwhelming it.

**Additional Elements:**

To the sides of Eren, two banners float gracefully in the air, their surfaces covered in intricate, Art Nouveau patterns, nodding to Beardsley's influence. The banners contain handwritten birthday wishes, each letter painstakingly crafted to match the overall style of the card.

The entire scene is framed with a delicate border of entwined vines and flowers, inspired by Edward Gorey, creating a subtle yet enchanting finish to the card.
