Sabueso Infernal de Dos Cabezas a la Carga

A dramatic monochrome fantasy illustration of [Orthrus], a massive two-headed hellhound charging straight toward the viewer through a dense ancient forest. The creature has exactly two snarling canine heads: the left head faces forward with jaws wide open, long fangs exposed, tongue visible, ears raised, and spiked fur bristling; the right head is positioned slightly behind and turned toward the right, roaring with sharp teeth bared. It possesses a muscular wolf-like body with thick shaggy black-gray fur, massive clawed front paws lunging over fallen logs, a curling tail on the left, and heavy spiked metal collars, rings, and chain links around both necks. The chaotic woodland setting includes towering tree trunks, tangled branches, leaf litter, splintered deadwood, boulders, and airborne dust and debris kicked up by its stride. Low frontal perspective, tight framing, dynamic motion blur, and a sense of imminent attack. Gritty black-and-white ink, charcoal, and graphite crosshatching with dense scratchy linework, high contrast, rough paper texture, and deep expressive shadows. Pure monochrome, no color, no borders, no text, square composition.
