Plan travelling fluide d'un coursier urbain

Create a 15-second photorealistic cinematic animated urban adventure sequence following a young bicycle courier navigating a busy modern city during a fast-paced delivery run.

Begin with a low-angle street-level establishing shot of a dense downtown avenue surrounded by towering skyscrapers, yellow taxis, city buses, cars, traffic lights, pedestrians, street signs, and realistic urban details → smoothly reveal the young male courier riding directly toward the camera through traffic, wearing a black bicycle helmet, orange short-sleeve delivery jacket, dark pants, gloves, and a large red insulated delivery backpack, maintaining the exact same character design, face, clothing, bicycle, and proportions throughout every shot → transition into a dynamic rear tracking shot as he weaves carefully between moving vehicles, with realistic wheel rotation, body balance, road friction, suspension movement, and subtle handheld camera motion → cut to a dramatic side-angle shot as traffic rushes past him while he accelerates through the intersection, creating natural cinematic motion blur → transition into a wider urban shot as he approaches the sidewalk and smoothly lifts the front wheel, riding up toward the curb while pedestrians react naturally → follow with a dynamic low-angle tracking shot as he rides along the busy sidewalk, passing pedestrians, street furniture, storefronts, and city infrastructure with believable depth and scale → cut to a dramatic elevated angle as he crosses back toward the street and continues the delivery route through the dense downtown environment → transition into a fast cinematic side-tracking shot showing the courier cycling confidently beneath massive skyscrapers while vehicles move around him → final shot becomes a heroic wide-angle cinematic frame with the courier riding across the foreground beneath towering city buildings, warm afternoon sunlight reflecting between skyscrapers, long realistic shadows, atmospheric depth, and the city continuing to move naturally behind him.
