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 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.
