Cosmic Sentinel Galactic Poster

An imposing female cosmic superhero in her late twenties, featuring a lean muscular build, radiant golden skin tone, and an aura of supreme command, wearing a pristine iridescent titanium battle suit with raised celestial star patterns, glowing magenta micro-fibers, a flowing deep indigo cape woven from starry nebulas, and an illuminated crystal chest insignia emitting soft violet light. She stands triumphantly atop a shattered asteroid floating in outer space, with a swirling purple ringed galaxy, distant glowing supernovas, and shimmering cosmic dust clouds stretching across the backdrop, while floating space debris creates foreground depth. The lighting is dominated by a dramatic celestial split light source, casting intense violet and hot pink rim lighting on her metallic armor while warm golden starlight soft-lights her resolute face and focused expression. She is captured in mid-gesture, extending one glowing hand toward the viewer as crackling energy arcs off her fingertips, her expression fierce yet noble. The shot is framed as a low-angle cinematic movie poster composition, using the rule-of-thirds to position her heroically against the galactic background. Captured with a virtual 35mm wide-angle anamorphic lens at f/2.8, creating rich bokeh on distant stars and subtle horizontal lens flare across her chest emblem, presented in a high-contrast graphic novel cover style, fine ink cross-hatching detail, vivid comic book color grading, hyper-detailed 8K digital painting.
