Greetings @FabioGC !
Ya see, from the stills, your project looks like an urban area at nightfall. Impressively built? Yes. Dangerous thoughts? No, not at all. But when I watched the cinematic…oh! 
Brilliant way of using camera movement along with background noise and ambient sounds to tell a story (as our @PresumptivePanda pointed out)!
A sense of panic came across me as the sound of a vicious pooch barking continued, and we passed by a metal barrel bonfire, and the space in the alley seemed to get smaller and smaller, and just when the claustrophobia came to toward a peak, we get the scary crescendo from something lurking in the shadows! Nope! 
This was extremely enjoyable to watch! Talk about a break from Archviz! In letting your creativity flow, you’ve delivered us a brilliantly atmospheric nightmare! For this, I thank you! [insert gracious bow]
Did you draw from any source of inspiration for The Alley?
