Monochrome digital sketch in a high-fantasy art

A detailed, monochrome digital sketch in a high-fantasy art style, showing a massive, monstrous beast from a low-angle perspective, its huge, segmented, toothed maw and scaled neck dominating the foreground and wreathed in dramatic, swirling plumes of ethereal, smoke-like light. A rider, depicted from behind, sits high on the creature's back, wearing intricate armor and a large, flat, circular wide-brimmed hat. The rider holds the reins in their left hand, pulling back, and wears a visible medallion. The entire scene is set in a desolate, rocky landscape under a dark, stormy sky, with heavy, charcoal-like digital brushwork creating texture and a sense of wind-blown dust and particles. The atmosphere is intense and moody, rendered with deep blacks, a range of grays, and bright white highlights. Beast has red glowing eyes.
