Generate a sequence of 6 atmospheric city alley scenes that all take place in the same narrow street, with consistent architecture, signs, perspective and overall style.
Style: realistic photography with a slight cinematic film look, soft grain, subtle lens bloom, inspired by Japanese backstreets.

Scene 1 – Early Morning: the alley is quiet and almost empty, cool blue light, shutters half-closed, a faint mist on the ground.
Scene 2 – Late Morning: shops are open, warmer sunlight enters the alley, a few people walking and bicycles parked, brighter colors.
Scene 3 – Golden Hour: warm orange light from the low sun at the end of the alley, long shadows, vending machines glowing softly.
Scene 4 – Blue Hour: sky is deep blue, shop signs and lanterns turn on, reflections on slightly wet pavement.

Keep the street layout, buildings, signs and vantage point consistent across all 6 images so they feel like different times of day in the exact same location

Generate a set of 3 consecutive illustrations in a gritty action-anime style: first, a lone rider speeds through a shattered desert highway on a futuristic motorcycle, pursued by armored raiders. The next illustration shows an intense mid-air leap over a collapsed bridge as explosions erupt behind them. The final scene captures the rider skidding to safety atop a cliff, raising dust while the burning wreckage of the pursuers lights up the wasteland below.
