Create an image of an elderly male miner with deep wrinkles and a rugged, weathered face covered in soot. He should have intense, piercing blue eyes and a grey, unkempt beard. His expression conveys years of hard work and determination. The man is wearing a miner�s helmet, suggesting his profession, and the lighting casts dramatic shadows across his features, highlighting the texture of his skin and the fatigue in his eyes. The background should be dark to emphasize the subject.
