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 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 tap. The tap is made of shiny metal and has a curved shape that points downwards. At the end of the tap, where the water normally comes out, hangs a single drop of water that is about to fall. Another tap can be seen blurred in the background to the left of it. The entire background of the picture is blurred and shows a mixture of green and blue colours that could be reminiscent of an outdoor area or a garden. The light in the picture is warm and appears to be coming from the top left, casting a soft, golden glow on the tap. This creates a feeling of freshness and clarity, as if it is a sunny morning. In the foreground of the image, below the tap, there is a blurred area which may represent a sink or basin.

The picture shows an intimate moment in a brightly lit room. In the foreground is a couple in a loving embrace in front of a large window. The man is wearing a brown top and beige trousers, while the woman is wearing a light-coloured top and dark trousers. Both people are standing barefoot on a wooden floor, with the man standing slightly behind the woman and embracing her tenderly. The window, which takes up most of the background, allows plenty of natural light into the room and offers a view of a wooded outdoor area. The sunlight streams through the window and creates warm rays of light in the room. To the left of the picture, near the window, is a table attached to a wall. There are two small objects on the table, presumably salt and pepper shakers. To the right of the window is a large houseplant in a white flower pot. The plant is clearly visible and lends the room a natural atmosphere. In the right-hand part of the picture, further in the background, there is a piece of wooden furniture that looks like a wine rack or a small shelf. There are a number of objects on the shelf, including a framed picture and other decorative items.
