One of the most important and simple rules that you need to keep in mind all the time. As large as possible to see all the details (this is always interesting to the viewer) and as wide as possible to give a complete picture of the city.
The significant difference between close-up and super-wide shots is very important. The more the difference, the more spectacular the final video will be. Even when it seems that the shot is close enough, it is advisable to try and shoot even closer and the same with wide shots.
