From the citizens’s point of view
If you have the Free Camera mods for Cities Skylines you are able to drop down to citizen level and either walk around from the view-point of a person or follow any vehicle whether on land, sea or in the air. The great thing about this is along with the Screenshots button (F12) you get to see your city down at a personalised level. At the same time if you click on individual citizens or tourists they tell you their happiness and where they are going. This can allow fine tuning while enjoying the City as a person would see it rather than how most see it at 40,000ft.
Below is some citizen level and follow the bus shots going around Layton City. For full resolution right-click the individual picture slide and open in a new tab.
