A terrifying demon with a grotesque and deformed face, featuring deep

A terrifying demon with a grotesque and deformed face, featuring deep, sharp cracks and hollow, dark eyes. The demon's skin is rough and mottled, resembling cracked stone, with sharp, uneven teeth exposed in a horrifying scream. Its head is twisted, with gnarled and misshapen features, and the skin pulls tight across its bones, creating an eerie, skeletal appearance. The creature's body is hunched and muscular, with sinewy, leathery skin that seems almost fused with its skeletal structure. The background is dark and foreboding, with subtle shadows to highlight the demon's nightmarish form.
