Public Health Institute Mosaic

It was a hard one.
The Public health institute situated in Kiev, Ukraine.
I wanted to grab it as much detailed as I can from the ground.
This is a raw decimated model, the original scan goes to 475 mil faces from 802 photos.
Shots were taken in a hard, from sun to clouds environment with the different focus distance.
Last photo taken from Google Maps.
Think I've got it.
