Witch Conjuring a Demon in a Misty Swamp

An extremely evil ancient Grand Dark Witch stands on a mystical ancient stump carved with runes, conjuring a hideous demon with large leathery wings, a sinewy body with striated musculature, large coal-black eyes, no nose, and an open maw full of sharp, crooked fangs. The demon rises from a stifling, moss-covered swamp in a deep, dark bayou, reaching with leathery hands and long, black claws. Pervasive mist hangs in the air as the witch displays her awesome power. Dark, terrifying horror art concept art style, extreme detail, muted lighting to show intricate detail, cinematic depth, with influences from Hieronymus Bosch, inspired by Zdzisław Beksiński.
