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.

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.
