Sure, here's a short descriptive passage about a winter night snowy alley, with a word count of no more than 100 words and a focus on creating a vivid image:
In the winter night's snowy embrace,
A narrow alleyway glistens with grace.
Soft flakes fall, like diamonds in the sky,
Blanketing the cobblestones, a winter wonderland lie.
The alley's twists and turns, a secret hideaway,
Where snow-covered roofs, a peaceful sight, do stay.
The silence broken only by crunching feet,
A magical winter scene, pure and sweet.
