Front and center of the greeting card, illustrate a large, exaggerated, cartoon-style birthday celebration taking place in the heart of Cologne. At the foreground, create a bustling crowd of colorful cartoon characters with large, exaggerated heads, all smiling and wearing party hats of various shapes and sizes.

Position a gigantic birthday cake in the middle, decorated with vibrant layers of pastel pink, blue, and yellow. The cake is topped with an oversized, twinkling candle shaped like the iconic Cologne Cathedral, adding a unique twist. Use a bright red banner that arcs across the top of the cake with the word "Verena" boldly written in white frosting.

In the background, sketch the famous Cologne Cathedral with cartoonish proportions—its spires towering into a clear, azure sky. Add fluffy white clouds above, with a group of lively cartoon birds wearing tiny party hats flying across.

To the left, include a traditional German pretzel stand manned by a friendly character with an exaggerated mustache, offering giant pretzels with mustard. On the right, draw a street musician, a comically large tuba around his neck, playing cheerful notes that float like colorful bubbles through the air.

Sprinkle the scene with confetti in primary colors, adding a sense of motion and festivity. Finally, set the entire illustration on a cobblestone street, subtly echoing the historic charm of Cologne, but in a vibrant, playful, cartoon style.
