The picture shows a corner of a housing estate with white modern apartment buildings stretching from left to right across the picture. The buildings are characterised by an unusual architecture, as they alternately have protruding cubes with either large windows throughout the whole cube or set in balconies. The skyblue sky is filled with a few white clouds on the right side of the picture and in the foreground are red hedges and small trees that have been planted around the buildings, marking the property of the apartment buildings. There is a paved pedestrian path along the hedges and this is also bordered by another green hedge. The pedestrian path runs in a half circle in the bottom right of the picture, making a way through the grass that is planted there.

The picture shows a man sitting on a balcony in an urban environment. He is wearing a dark blue suit and a white shirt and is sitting relaxed at a small black table on the lower half in the centre of the picture. On the table in front of him are a laptop, a notepad with a pen and a coffee mug. The man has rested his legs on the balcony railing and is holding a telephone in his left hand while talking on the phone. The balcony is richly decorated with plants. On the left of the picture, climbing plants stretch up the wall, taking up almost the entire left side of the picture. Below the climbing plants are several pots of flowering plants and greenery arranged along the floor of the balcony. Above the man, stretched across the balcony, is a string of lights with several light bulbs that extends from the top left-hand corner to the right-hand side of the picture. In the background you can see a row of multi-storey buildings in various shades of yellow stretching across the top and centre of the picture. Behind the buildings is a park-like landscape with many trees that further break up the background. The sun seems to be either rising or setting, giving the picture a warm, golden glow. The view from the balcony extends over the roofs of the city.

The picture shows a green, wide and tall meadow with large green trees on the edge of the horizon in the upper third of the picture and a girl running through the meadow. From the upper edge in the centre, bright yellow rays of sunlight stretch across the middle of the picture and bathe it in warm light. In the centre of the picture, a little girl in a knee-length, sleeveless white dress is walking across the meadow with her back to the viewer. Her long blonde hair blows away from her body to the left as she moves. In addition, as she runs, her left arm is loosely behind her back and her left foot is bent upwards so that the entire underside of her foot can be seen at the end of her dress.

Since the photo was taken from a frog's-eye view, you can see a tall, modern office building made of light-coloured stone with four rows of large windows in the background.
