Create a lino cut style image of an old man in a front view, looking directly at the viewer. The man's face should express wisdom and the passage of time, with deep-set eyes, weathered features, and a thoughtful expression. His clothing is simple yet timeless, suggesting a life of experience and contemplation. In the background, depict rolling hills that convey a sense of peaceful isolation. However, the sky above these hills should be dark and ominous, adding a dramatic contrast to the scene. The color palette for the image should be restricted to shades of blue, black, dark green, and greys, evoking a mood that is both serene and foreboding. Pay special attention to the lino cut style, emphasizing bold lines and contrasting textures to capture the essence of this printmaking technique. The composition should balance the detailed portrayal of the old man with the sweeping landscape and brooding sky, creating a harmonious yet impactful visual narrative. --v 6.0
