A photorealistic image of a young professional woman holding a smartphone to her

A photorealistic image of a young professional woman holding a smartphone to her ear as if receiving a call. She is smiling warmly and looks engaged in conversation. The woman should be wearing business casual attire, perhaps a blouse and blazer. She is standing in an office or home office setting with soft, natural lighting. The focus should be on her face and the phone, with the background slightly blurred. The image should have high resolution and look like a stock photo or professional photography, not an illustration or cartoon. Also make sure you can see her waist up.
