**Front Cover Design Description:**

**Background & Layout:**

- The scene is set against a vibrant turquoise sky, a flat color with no gradients to maintain the vector style.

- Two fluffy, minimalist white clouds drift in the upper part of the card, slightly off-center to the left and right, providing a visual frame for the birthday theme.

- A large, circular sun with a warm gradient from lemon yellow to soft orange is positioned slightly towards the top left, casting no shadows, to keep the crisp flat look.

**Central Elements:**

- At the center of the card, a large, three-tiered birthday cake stands proudly. The cake's tiers are a blend of pastel colors; the bottom tier is mint green, the middle tier is lavender, and the top tier is pale pink. Each tier is decorated with flat, vector-style geometric patterns such as triangles and polka dots in contrasting colors like white, yellow, and blue.

- The cake is topped with a single, oversized, red-orange candle, lit with a stylized flame using a flat orange and yellow gradient.

**Additional Details:**

- A bright, rainbow-colored banner stretches across the width of the card, slightly below the sun and above the cake. The banner features flat, vector text in a bold, modern sans-serif font: "Happy Birthday".

- On the side of the cake, a small, flat vector-style present is placed. The present is wrapped in cobalt blue paper with a bright red ribbon, maintaining a minimalistic design.

**Text Element:**

- Below the cake, a decorative ribbon in a rich, royal blue color is placed, and in the center of the ribbon, in sleek, white vector lettering, reads "Mr. Serge P. Kuate". The text is concise, clean, and positioned to stand out against the bold ribbon color.

**Additional Features:**

- Scattered around the cake and present are flat, vector-style confetti shapes in colors like vibrant yellow, teal, and coral, creating a sense of celebration without overcrowding the design.

- There is no shadowing or gradients used in other elements besides the sun, to adhere to the clean, flat vector style inspired by the artists mentioned.

This design maintains a modern and playful aesthetic, using concrete shapes, bold colors, and simple forms to create an engaging and eye-catching birthday greeting card cover.
