The doors are an easy fix, unless you have a back story to explain them. The rest of the building and street are quite well done. You may want to account for drainage from the roof of the building. Without gutters and a down pipe, water tends to accumulate at the corners of buildings. This includes the balcony. If it weren't for the doors, it appears to be a building from the Soviet block. Several of this type of building style is found in Russia, abandoned. Depending on the time frame, you could put up propaganda posters to distinguish it. Archer makes some wall slogans(
