Art style: Cinematic Realistic.
The moment of the surprise: lights turn on, colorful confetti and streamers explode in the air, the three friends jumping out from hiding with joyful screams, while Polina gasps in pure delight with hands to her cheeks, beaming with happiness, vibrant festive party atmosphere.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cinematic Realistic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cinematic Realistic". 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 "Cinematic Realistic" idiom, not in any other medium.
