The scene is a vibrant, dynamic collage of a 21st birthday celebration, set against a whimsical cartoon backdrop inspired by the eclectic styles of famous illustrators.

**Background:** The setting is a playful version of Berlin, with the iconic Berlin Wall exaggerated in cartoon form, stretching across the horizon. The wall is humorously painted in bright graffiti colors, with balloons tied to the top. A surfboard leans casually against the wall, its vibrant colors echoing those of the wall's graffiti—electric blue, neon pink, and lime green.

**Foreground Elements:**

1. **Stella Artois Beer:** Front and center is an oversized, cartoonish Stella Artois beer bottle. Its label is illustrated with exaggerated details, the red and white logo popping against the bottle's glossy amber. The bottle is tipped as if it's pouring out a frothy wave, mimicking a surfable ocean wave.

2. **Frisbee:** A larger-than-life frisbee zooms across the scene, mid-air, its edge decorated with colorful 21st birthday motifs like confetti and mini party hats. The frisbee is animated with bold lines, trailing a swoosh of motion lines to imply speed.

3. **Surfers:** Riding the frothy beer wave are tiny cartoon characters, complete with surfboards. They are depicted with large, expressive eyes and exaggerated features, reminiscent of Osamu Tezuka's manga style. The surfboards are decorated with mini versions of iconic Berlin landmarks.

4. **The Berlin Wall:** Peeking out from behind the beer wave is a cartoon section of the Berlin Wall, with its top lined with colorful flags of various countries, hinting at a global celebration.

5. **Text Element:** Above the scene, a sky banner flies with the word "Mark" in bold, playful letters. The banner flutters in the cartoon breeze, anchored to the surfboard by colorful strings.

**Color Palette:** The overall color scheme is bright and lively, featuring primary colors mixed with bold pastels. The sky is a clear, animated blue with fluffy, stylized clouds. Each element has thick, defining outlines, giving it a classic comic strip feel, blending influences from Schulz's simplicity and Watterson's lively expressiveness.

This birthday card front cover encapsulates a festive atmosphere, using exaggerated features and vibrant colors to create a memorable and humorous visual story.
