Create a hyper-realistic 4K scene of a muskox standing on a frozen tundra, looking directly at the camera with a calm yet imposing gaze. The muskox's thick, shaggy coat of dark brown and cream-colored fur is intricately detailed, with individual strands visible as they move slightly in the cold wind. Its large, curved horns are weathered and textured, adding to its majestic appearance. The backdrop features a vast, icy landscape with snow-covered ground and distant, jagged mountains under a pale, overcast sky. The lighting should emphasize the muskox's rugged strength and its adaptation to the harsh Arctic environment.
