Gigantic troll with brutal features in a rugged mountain wilderness

Create an image of a gigantic troll, between 2.50 and 4 meters tall, with a massive build. Its body should be broad and robust, with thickened, muscular limbs, demonstrating its immense strength. The troll's face is rough, broad, and angular, with strong features and thick, often wrinkled or rough skin. Its eyes are small and piercing, dark in color, expressing a brutal intelligence. Add a prominent, broad, and flattened nose, which reinforces its bestial appearance. Incorporate large, sharp teeth, sometimes visible even when the mouth is closed, accentuating its menacing appearance. Its skin can vary in color, from green to gray or brown, with a texture similar to stone or earth. For the hair, show it as sparse, shaggy, and untidy, in dark or bleached tones. Dressed in rudimentary clothing made of animal skins or tattered fabrics, the troll should convey a sense of brute strength and wild power. Place it in a natural environment, such as a dense forest or mountain, to emphasize its imposing and rugged character.
