The picture shows a close-up of the keyboard of a laptop, which is illuminated by warm rays of sunlight from the background. The screen of the laptop is on the left edge of the picture and a woman in a dark blue shirt can be seen sitting in a blur on the right edge. Her hands are resting lightly on the keys of the laptop. The background of the picture is very blurred, but you can easily recognise the walls of a room and a window through which the sun's rays shine.

The picture shows a row of narrow but tall terraced houses. The terraced houses have alternating grey and white façades. On the left you can see a house with a white façade and on the far right a house with a grey façade. They are also always built at different heights, so that there are never two houses of the same height next to each other. All the houses have a large square window front in the upper half, consisting of 30 small square windows. The window front of the fourth house from the right is the only one covered by a blind. All of the houses have four individual windows under the fronts, with two on the left and two on the right below each other. Above the houses you can see the almost completely cloudless blue sky. In the foreground in front of the houses you can see a lawn with many bushes and a total of four trees, three of which can be seen on the left at the edge of the picture and one tree on the right.

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.

The picture shows a young man leaning against a glass railing and holding a small tablet with a white cover in his hand. He is smiling and looking into the distance. The man has short brown hair and a short brown beard and is wearing a beige suit with a white t-shirt underneath. 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.
