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.

Behind the man, to the right of the picture, is a large floor-to-ceiling window that allows plenty of natural light into the room. A green garden with lush vegetation can be seen through the window. Next to the window is a large plant in a pot on the floor. To the right of the plant is a black radiator, which contrasts with the light and natural colours of the room. To the left of the man, part of a beige sofa is visible. Other parts of the room can be seen in the background on the left of the picture, possibly including a door or another window, which also bring light and space into the room.

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 smiling woman with blonde hair and glasses standing in a modern office. She is wearing a cream-coloured blouse and has her arms crossed in front of her chest. The woman is in the centre of the picture. Behind her, a wall is covered with lush green foliage growing in a wooden frame. This green wall takes up the left part of the background and gives the room a natural and lively atmosphere. To the right of the woman, along the right side of the painting, is a window front that allows plenty of natural light into the room. The windows show a view of the roofs and the surroundings outside the building. A blur is visible in the foreground of the picture, possibly created by a glass surface or reflection. This blurring gives the image a certain depth and a modern photographic effect. The whole scene conveys an image of a modern, well-lit and green working environment that is both professional and inviting.
