what details in the physical description of zaroff foreshadow the truth about his nature ?

bizarre, sharpcut, the face of a man used to giving orders

"Rainsford's first impression was that the man was singularly handsome; his second was that there was an original, almost bizarre quality about the general's face. He was a tall man past middle age, for his hair was a vivid white; but his thick eyebrows and pointed military mustache were as black as the night from which Rainsford had come. His eyes, too, were black and very bright. He had high cheekbones, a sharpcut nose, a spare, dark face--the face of a man used to giving orders, the face of an aristocrat."

pointed teeth- carnivorous; beastlike

"He is a Cossack," said the general, and his smile showed red lips and pointed teeth. "So am I."
