All cities seem to have these kind of faceless buildings. Square cold buildings. They actually make a good canvas when reflecting the sky. This is my idea of how one of these buildings would look during a storm. The power would have to be out so that no light would shine to the outside. I used varnish only on the building to make the "glass".
