Generate a realistic photo of a guy named Alex. The image should depict him standing in a natural environment, with his upper body visible from the hips up. Alex is an average-looking man in his mid-30s, with short dark hair beginning to show a hint of gray, and hazel eyes. He possesses a friendly, approachable demeanor, with a modest smile that reflects his easygoing nature. He dresses casually in a shirt with a summer look, not too flashy but appropriate for the season. The natural background should be serene and unobtrusive, perhaps a wooded area, a field, or beside a gentle stream, mirroring Alex's connection to the outdoors
