There is an open laptop on the table in front of him. Next to the laptop is a blue coffee cup.The background of the workshop is blurred, but you can recognise shelves and tools that indicate a manual or creative activity. The light streaming in from the right through a window illuminates the scene and creates a warm, inviting atmosphere.The man appears focussed and content, which is conveyed by his smile and relaxed posture.
