Vertical full-bleed image, native source proportions 673:1200. Very tight abstracted crop of a large feathered wing running vertically down left two thirds. Its long closely stacked cream-gray feathers form curved repeating bands that bend from top left to lower middle, undersides lit muted red-orange near bottom. At x67%,y48% a small pale twisted humanoid or clawlike shape emerges from blackness, detail ambiguous; keep it small rather than inventing a large clear head. Upper right and center are almost black. No full symmetrical angel, no bright backdrop or explicit face. Prioritize rhythmic feather arcs and dramatic negative space.
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.
