Bradhamel art style, masterpiece, burstdaal, WatercolorInks, Nightjar Illustration, dcd@rkf@ntsy. An adult armored duke crouches on the raised wooden arm of a ruined trebuchet. A huge wedge of black raven feathers covers his shoulders and trails backward along the beam. His human-sized helmet has a long narrow beaked visor and a low serrated crest. A red strip of cloth hangs from his throat over black plate armor. One gauntlet grips the beam while hooked armored boots hold his crouched position. Closed waist and leg armor over opaque trousers completely cover his lower body. Low-angle full-body view with the feather mantle clearly outlined against a pale winter sky. The trebuchet arm rises diagonally beneath him; its heavy timber base remains visible below. Distant broken battlements form a low horizon. Hand-drawn dark fantasy boss illustration with sharp black silhouettes.
