Mythological Fallen Angel Dark Fantasy Poster

An dark mythological fantasy poster illustration featuring a fallen angel crouching atop a ruined white marble pedestal under a vast moonlit night sky, depicting a male warrior figure in his late 20s with athletic sculpted physique, fair skin marked with faint glowing silver runes, and giant dark obsidian feather wings spanning outward with loose feathers drifting downward, head bowed in solemn reflection with dark silver hair falling forward, wearing tattered dark leather wraps around his waist and forearms, backlit by a gigantic silver full moon that illuminates the feather tips in stark luminescent rim light while casting the front of his figure in deep sculptural shadow, cool blue midnight sky filled with distant swirling nebula clouds, dramatic centered composition with low-angle hero perspective framing, shot as a digital fantasy artwork render with octane texture depth, hyper-detailed feather textures, glowing magic dust motes, deep indigo and stark white color scale, atmospheric dark fantasy poster style.
