In this vibrant and whimsical illustration, imagine a joyous birthday scene set in a split-background to emphasize the theme of a long-distance relationship between Thailand and London.

**Background Elements:**

On the left side of the card, depict a serene Thai landscape. Include a detailed depiction of a traditional Thai wooden house surrounded by lush greenery and delicate frangipani trees. In the sky, draw a flock of swallows fluttering gracefully. This section should be vibrant with tropical colors like lush greens, vivid yellows, and warm browns.

On the right side, capture a classic London setting with iconic red double-decker buses and a silhouette of the Tower Bridge in the background. The sky is a gradient of gentle dusk tones: pale blues blending into soft pinks, suggesting an early evening in the city.

**Central Characters:**

In the middle of the card, bridge the two landscapes with a ribbon-like road or path lined with delicate cherry blossoms. Walking down this path, illustrate the Thai lady, elegantly dressed in a traditional silk outfit with vibrant golden patterns. Her long black hair flows freely, adding a sense of movement.

Beside her, portray the handsome English guy with a kind smile, wearing casual attire: a blue shirt and khaki shorts. His short brown beard is well-groomed, and his glasses catch the light.

By their feet, draw a playful white cat with ginger and black splotches. The cat sports a red collar with a tiny golden bell, creating a charming focal point.

**Text and Creative Elements:**

Incorporate the text "Poppy" artistically into the scene. Perhaps it's spelled out in the path of swallows, or it appears subtly in the wisps of the cat’s tail curling into letters.

In the sky, stretch a cheerful banner arcing across the card that reads "Happy Birthday" in a whimsical font, accented with tiny stars and confetti. The banner ties together both landscapes and adds a sense of celebration.

**Overall Style:**

The style is rich in detail, echoing the precision of Norman Rockwell and the whimsical charm of Quentin Blake. The colors are vibrant yet harmonious, creating a sense of unity despite the distance portrayed. The drawing should feel alive with intricate line work reminiscent of Arthur Rackham's illustrations, yet maintain the playful air seen in Beatrix Potter's animal characters.

This imaginative blend of cultures, settings, and playful details ensures a lively, heartfelt birthday greeting card that celebrates both distance and togetherness.
