The picture shows two men looking intently at a laptop. The man on the left has curly, dark hair and a beard, while the man on the right has shorter, lighter-coloured hair. Both are wearing shirts, with the man on the left wearing a dark-coloured shirt and the man on the right a light-coloured shirt. They appear to be engaged in a conversation and are possibly working on a project together. There are blurred green leaves in the foreground, suggesting a leafy or natural environment. The background is blurred, but it can be recognised that they are in a modern office or workspace. You can dimly make out office furniture and shelving, suggesting a professional environment.

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.
