The front cover of this birthday greeting card is a lively and colorful cartoon scene, bursting with whimsy and detail, drawing inspiration from the iconic styles of classic cartoonists.

In the foreground, an animated otter stands on its hind legs, its expressive eyes wide and sparkling with playfulness. Its fur is a soft caramel brown, with a creamy white underbelly. The otter holds a vibrant blue speech bubble above its head with one paw, in which the words "Happy Birthday, Alex!" are written in bold, playful lettering, reminiscent of Bill Watterson's carefree style.

The otter is perched atop a giant birthday cake that takes center stage, almost as tall as the otter itself. The cake is a cascade of pastel colors: a lavender base with alternating tiers of mint green and buttery yellow, all covered in frothy white icing that drips down the sides. Each tier is dotted with a variety of colorful candles in shades of pink, orange, and teal, their flames flickering with a soft, warm glow.

Surrounding the cake is a whimsical water scene, channeling the clean lines and vibrant hues of Hergé. Brightly colored water splashes playfully around the base of the cake, in shades of turquoise and aquamarine, giving the impression of gentle waves that reflect shimmering highlights like a cartoon sea.

Scattered around the scene are floating heart-shaped balloons, each one a different pastel shade—pink, lavender, sky blue, and lemon yellow—adding a touch of Osamu Tezuka's dynamic energy to the card. The balloons are tethered to the cake with delicate strings that dance in the imagined breeze.

The background is a simple, bright sky blue, speckled with fluffy white clouds that resemble Charles Schulz’s signature doodle-like clouds. This serene backdrop allows the vibrant details of the scene to pop and create a sense of cheerful celebration.

The entire composition has a playful exaggeration typical of Gary Larson's work, with exaggerated features and a charming sense of chaos that makes the scene feel alive and joyous, capturing the imagination and setting the perfect tone for a birthday celebration.
