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.
