Create a hyperrealistic portrait with artistic flair inspired by Caravaggio's chiaroscuro technique. The subject is a seasoned sailor, his face rugged from the sea, his intense blue eyes standing out against a dark, stormy seascape. Light emanates from behind, casting dramatic shadows across his lined visage, highlighting a furrowed brow, while deep shadows surround him, creating an atmosphere of brooding. This portrait captures the complex emotions of a sailor's life: the weariness of long voyages at sea blends with resilience in the face of nature's fury, evoking a range of emotions from melancholy to awe.
