Art style: Children's Book.
A cinematic split-screen scene showing Regina in Paris and Vali in Austria, separated by distance. Regina is celebrating her birthday in Paris, surrounded by beautiful Parisian streets, warm evening lights and subtle birthday decorations. She is dressed stylishly and holds her phone, reading messages from Vali. Although she is surrounded by the beautiful city, she looks emotional and misses him. On the other side, Vali is sitting alone in Austria, looking at his phone and texting Regina. Their phone screens subtly connect the two sides of the image. Romantic but melancholic atmosphere, polished animated cartoon style, expressive faces, cinematic lighting.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Children's Book" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Children's Book". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Children's Book" idiom, not in any other medium.
