A Grimdark Warhammer 40k Sister

A grimdark Warhammer 40k Sister of Battle, medium shot, walking forward through a desolate, war-torn city street in heavy rain. She wears black power armor with red accents, white fleur-de-lis and skull emblems, and carries a bolter. The background features ruined, dark buildings with broken windows. Heavy, dark clouds of smoke or fog obscure the foreground and ground level. Comic book art style, ink outlines, muted, desaturated colors (grays, dark blues, browns, reds), dramatic and somber mood. Overhead, dark, rainy sky. Heavy hatching and gritty textures.
