In the center of the card, draw a grandiose underwater scene brimming with life and mystery. The focal point is a detailed U-Boat submarine crafted entirely from Legos, its vivid colors of yellow, blue, and red piecing together the illusion of a formidable vessel navigating the depths. This submarine emerges prominently from the bottom of the card, the blocks meticulously illustrated to highlight their studded tops and interlocking seams.

Surrounding the submarine is an enchanting underwater landscape, a kaleidoscope of aquatic hues: rich cobalt blues for the water, with shimmering shafts of light breaking through to reveal vibrant seaweed in lush greens and swaying corals in pinks and purples. Schooling fish, depicted with quick, fluid lines, dart around in shades of silver and orange, creating a sense of motion and life.

Above the submarine, a Lego-built birthday cake floats, impossibly large, with layers constructed from pastel-colored bricks: creamy whites, soft yellows, and light pinks. Brightly colored Lego candles stand erect atop the cake, flickering flames suggested by a clever use of orange and yellow blocks. Suspended in the water, bubbles, detailed with delicate strokes, rise upwards, capturing the light with subtle glints.

In the background, add an intricate arch formed from Lego bricks, signifying an underwater passageway, hinting at a mysterious adventure beyond. It's crafted in shades of brown and beige, reminiscent of a sunken shipwreck, detailed with aquatic plant life that wraps around its structure.

Incorporate the name "Michael" in an imaginative manner by using Legos to form a banner that floats above the submarine. The banner arches gracefully, with each letter individually crafted from Lego bricks in bold primary colors—red, blue, and yellow—contrasting against the watery depths, making it a prominent feature in the composition.

The illustration's style is a meticulous blend of Norman Rockwell's realism and Maxfield Parrish's luminous color palette, infused with Edward Gorey's intricate detailing. This unique combination creates a scene that is both whimsical and grand, inviting the viewer into a world of playful imagination and artistic mastery.
