Ultra-realistic portrait of a man in his 40s. He has brown hair with a few white

Ultra-realistic portrait of a man in his 40s. He has brown hair with a few white strands, a neatly trimmed beard and green eyes that reflect concern and determination. His face is well defined and his expression suggests seriousness and urgency. The portrait should be from the waist up. He is wearing a casual shirt. The man is in a domestic setting, holding a telephone. The environment should include a table and a window in the background, but should be blurred so as not to distract from the main subject. The lighting should be soft and natural, with morning light coming from a window, creating subtle shadows that accentuate the man's worried expression. The light should highlight the green eyes and the texture of the skin, emphasizing the seriousness of the situation. The image should convey a sense of urgency and concern, with a touch of tension. Suggest a warm color palette, such as golds and browns, that complements the atmosphere of the morning. The photo should be of high quality, with 8k rendering and extreme detail, capturing the emotional essence of the moment.
