Spaceship corridor walk

Prompt inspiration

Image-to-video prompt: preserve the exact first frame composition and identity from the source image. A lone female astronaut seen from behind walks steadily down a bright futuristic spacecraft corridor, holding a glossy black space helmet at her side. Subtle natural walking motion, gentle suit fabric movement, slight hair sway, helmet reflections shifting, blue floor light strips and ceiling panels gliding with parallax, overhead cable bundles barely swaying, polished reflective floor ripples with moving highlights. Slow cinematic dolly push forward following behind her, centered symmetry, deep vanishing point, cool cyan white sci-fi lighting with warm orange glow at the far doorway, premium high-budget science-fiction film look, realistic motion, stable anatomy, smooth temporal consistency, no cuts, no text, no logos, no watermark, 30fps finish, 12-second plus clip.
