person walking across a flat roof

person walking across a flat roof. The ground is rough, black, and possibly pebbly. A low white wall runs along the edge of the roof, with purple graffiti visible. In the background, there are trees and some buildings, with a cloudy sky above. As the person walks, they initially wear a white shirt, then appear to change into a blue shirt and carry a black backpack. They are holding a phone or similar device and seem to be taking pictures or video. The camera movement is shaky, likely due to the person filming while walking.
