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 relief and exhaustion. His face is well defined, and his expression suggests tiredness and relief. The portrait should be from the waist up. He is wearing a formal suit. The man is sitting inside a car, with the steering wheel and dashboard visible but blurred so as not to distract from the main subject. The lighting should be soft and natural, with daylight coming in through the car windows, creating subtle shadows that accentuate the man's relieved 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 relief and exhaustion, with a touch of dissipated tension. Suggest a neutral color palette, such as greys and blues, that complements the interior of the car. The photo should be of high quality, with 8k rendering and extreme detail, capturing the emotional essence of the moment.
