He wears a dark blue denim shirt and smiles broadly.The man is leaning over a large work table while holding a smartphone in his left hand looking at ista’s operating cost billing and making notes on the paper with his right hand. 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.
