I would assume on that statue of Augustus pictured painted, the breastplate would have at least a gold background, and his skin painted an attempt at fleshtone...
Statues of divine or semi-divine subjects often used ivory or white paint to give their skin a bleached/pale look. It would make sense that an image of the Emperor would also be given this appearance.
I'm not sure why, but I assumed ancient cities would be much more crowded.
The slow movement of people and goods within a city would highly encourage dense living conditions, something only strengthened by the high cost of building and the intrinsic crampness of city walls.
Cities should be shown bustling with people, but I feel like most artists aim is more about presenting the architecture or spacing of the buildings than the accuracy of the streets.
You also rarely see people bringing in agricultural goods or trade goods in these kind of paintings either.
