Front Cover Design for "Many Many Happy Returns of the Day" Birthday Card:

**Scene Layout:**

- **Background**: A clear sky with a gradient transition from a soft morning pink at the bottom to a serene sky blue at the top. A few flat, white, geometric clouds float in the sky.

- **Central Element**: A large, whimsical birthday cake composed of clean, flat shapes with crisp lines. The cake has three tiers. The bottom tier is a bright turquoise with polka dots, the middle is a vivid magenta with diagonal stripes, and the top is a sunny yellow adorned with small triangles.

- **Decorations**: Each cake tier is topped with candles—each candle a different color of the rainbow, with a small flame represented by a simple, flat orange and yellow teardrop shape. Around the cake, sprinkle a confetti-like scattering of geometric shapes in contrasting colors—circular dots, tiny triangles, and small squares in shades of lime green, coral, and lavender.

- **Text Element**: Above the cake, a stylized banner flutters across the sky. The banner is a crisp, flat white with the message "Many Many Happy Returns of the Day" inscribed in a bold, vector-style font. The text is colored in a deep navy blue.

- **Personalization**: Integrate the name "Mumthaz" creatively into the scene. The name "Mumthaz" can appear on a pennant banner draped across the top tier of the cake, with each letter on an individual flag. The pennant flags alternate in color between a soft lilac and light teal.

- **Additional Elements**: On the ground below the cake, place a vector-style gift box. The gift box is a rich plum color with a lime green ribbon and bow. Next to the gift box, add a party hat with the same design as the middle cake tier (magenta with diagonal stripes).

- **Outline and Line Work**: Use crisp black vector lines to define shapes and boundaries, ensuring the design maintains a clean, flat style reminiscent of vector illustrations by artists like Malika Favre and Matt W. Moore.

This design should maintain a playful, vibrant aesthetic with a clean, modern look, characteristic of the flat vector style seen in works by the mentioned artists.
