The front cover of the new-baby greeting card should be a lively maritime-themed scene, brimming with intricate detail and whimsical charm.

**Foreground**:

- **Ship**: A cartoonish, detailed pirate ship prominently sails across the lower part of the card. The ship's sails are big and billowy, each decorated with playful, pastel-colored baby icons—think rattles, pacifiers, and tiny boats. The wood of the ship is depicted in a warm oak color, with lots of hand-drawn wood grain details.

- **Crew**: Onboard, a group of animated, anthropomorphic animals—perhaps a rabbit in a sailor hat, a penguin with a telescope, and a parrot with a captain's hat—celebrate enthusiastically. They're playfully dressed in navy blue and white striped shirts, adding a classic maritime touch.

- **Banner**: Hanging across the ship's mast, a festive banner reads “Hello Baby Jonas” in swirling, vintage-style lettering. The letters are a cheerful sky-blue color, contrasting against the soft cream of the banner fabric.

**Middle Ground**:

- **Ocean**: The ocean is a dreamy pastel teal, with small, swirling white caps and bubbles illustrated in a style reminiscent of Arthur Rackham's delicate line work. Little rubber ducks and tiny toy boats bob alongside the ship, enhancing the playful theme.

- **Sea Life**: A pod of friendly dolphins and a smiling, cartoonish whale can be seen frolicking in the waves, painted in shades of soft gray and blue, detailed with delicate lines to indicate movement.

**Background**:

- **Sky**: The sky is a soft gradient of sunrise colors—lavender, blush pink, and peach—dotted with fluffy, hand-drawn clouds that have a hint of lavender shadow.

- **Sun**: In the top left corner, a radiant sun, illustrated with Beatrix Potter-style intricate lines, beams down on the scene. Its rays reach outward, detailed with lines that have a golden hue.

- **Seagulls**: A flock of seagulls, sketched in fine lines with a touch of Quentin Blake’s whimsical charm, flies overhead, their wings lightly tinted with blue and gray.

The card should capture the celebratory spirit with vibrant colors and imaginative details, drawing inspiration from the suggested artists without directly copying their styles.
