Vertical full-bleed image, native source proportions 673:1200. Full-body black horned winged figure stands centered on a mound of small ochre skulls across bottom12%. Long horns curve inward then outward to y2%, narrow head at y17%, dark robe tapers down to feet. Two enormous bat wings open from shoulders y26% and descend toward either lower edge, thin muted red-brown rib structure inside black membranes. Image-left hand holds a vertical narrow dark trident rising to y30%, other hand near waist, no extra limbs. Background saturated crimson orange sunset sky with layered dark red clouds, horizon low around y88%. Figure should remain almost silhouette, tiny warm flesh accents only. No multiple demons, bright feathers or moon.
Rendering: dark vintage fantasy print, matte fine grain, warm burnt orange light planes and deep charcoal robe silhouettes against painterly sky. Preserve observed object count, relative positions and negative space. No stylistic fusion, decorative border, platform UI, invented watermark or signature. Do not add unrelated props or colors.
