A brown bear is resting on a large rock, with its head down and eyes closed. The bear's fur is a rich brown color, and its paws are visible, with sharp claws. The rock is rough and textured, with a gray and brown color. The background is a forest or natural environment. The lighting is soft and natural, with the sun casting a warm glow on the bear's fur.
