**Foreground Details:**

- A cluster of animated investor characters in the style of Gary Larson, each holding a financial chart or tablet displaying stock tickers, wearing oversized glasses and comically large ties with bold patterns.

- A banner across the top of the card reads "Happy Birthday, Alex!" with the name "Alex" written in large, playful block letters adorned with confetti patterns.

**Color Palette:**

- A mix of bright primary colors inspired by early Walt Disney animations, with accents of pastels and bold lines reminiscent of Bill Watterson’s work.

**Miscellaneous:**

- Around the scene, tiny cartoon animals wearing birthday hats peek out from behind elements like the cake and Venn diagram balloons, adding a touch of Charles Schulz-style whimsy to the overall illustration.
