The picture shows a silhouette of a woman holding documents against the backdrop of modern skyscrapers. The perspective of the picture is from the bottom up, making the buildings look monumental and impressive. The woman is in the foreground of the picture, turned slightly to the left. Her profile is clearly visible and she appears to be looking intently at her documents. She is wearing a jacket and has tied her hair up in a bun. Several glass buildings can be seen in the background, taking up most of the picture. The building on the left of the picture is only partially visible, with a large round pillar extending upwards. The centre building is the most dominant and extends almost to the top of the picture. It has a glass and steel façade and reflects the sky. Another building can be seen on the right of the picture, which also extends upwards and forms a right angle to the centre building. The glass façades of the buildings give the picture a modern and urban feel. The sky is clear and slightly bluish, indicating a sunny or at least clear day.

The picture shows a modern lobby or waiting area with an impressive glass front that offers a view of an urban landscape. In the foreground of the picture are two plain black benches standing on a large beige carpet. The benches are arranged symmetrically to each other, one on the left and one on the right, leaving an empty space between them. The floor is made of polished white tiles that reflect the surroundings and the incoming light, creating a bright and inviting impression. The glass wall in the background consists of several tall, narrow panels that reach up to the ceiling and are connected by metal struts. Green, lush vegetation can be seen through the glass wall, contrasting with the tall, modern office buildings in the background. The buildings have different architectural styles and reflect the light in different ways, giving the scene depth and dynamism. The left side shows a striking building with a characteristic diagonal structure, while the right side shows several high-rise buildings with glass facades. The sun shines into the picture from the top right, bathing the scene in a warm, golden light.

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.
