Vertical full-bleed image, native source proportions 673:1200. Portrait distant full-body winged humanoid diagonally descends from upper right toward lower left. Pale sinewy torso crosses x48–83%,y38–54%, dark head bent down at x43%,y44%; one thin arm or rod stretches toward lower left. Huge black wings fill upper half with one arcing behind head and the other extending top right. Jagged cream-gray cliff or cloud masses rise along lower right, while lower left opens into smoky charcoal void. Body small compared with wing mass, no centered giant face, no orange flames, no bright sky. Preserve dramatic diagonal and uncertain trailing limb silhouette.
Rendering: dark classical mythological painting with tactile canvas grain, muted flesh highlights, deep black wing silhouettes and restrained ember red. 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.
