The picture shows a residential complex in the centre, stretching from the left to the right edge of the picture. The various buildings look very similar on the outside and have a white-orange brick façade. The individual flats have balconies with glass railings. The balconies are separated from each other by frosted glass walls and are furnished differently, giving each flat an individual touch. Most of the visible buildings have four floors, but vary in width so that different numbers of flats are visible on each floor. In the right quarter of the picture, in contrast to the others, another building rises up, which has the same style as the other buildings in the residential complex. A park can be seen in front of the residential complex in the lower half of the picture. Grasses and bushes surround the residential complex, accompanied by a pavement adorned with scattered trees. There are also benches and lanterns on the pavement. An artificial pond can be seen in the bottom left-hand corner, surrounded by a wooden walkway with glass railings. The sunset can be seen on the right-hand edge of the picture, giving the sky a slight colour gradient, from a reddish tone on the right to a bluish tone on the left.

While his right hand is in his trouser pocket, he is holding a closed laptop in his other hand. He is leaning against a door frame that leads to a corridor in the background. Several doors can be seen on the left-hand side of the corridor, indicating various offices.
