Solitary Astronaut in Endless Ocean Poster

Full prompt

Cinematic 35mm film still in a cerebral sci-fi documentary aesthetic, featuring a lone astronaut in a detailed white spacesuit standing quietly in vast, ankle-deep ocean waters. The astronaut is turned slightly in profile with a reflective, bowed head beneath an oppressive canopy of cold grey clouds. Shot from a low-angle wide shot with a lowered horizon, featuring soft, diffused cold lighting, low saturation, deep cyan-tinted shadows, and delicate film grain. The composition is restrained, tranquil, and rigorously balanced with modernist minimalism, preserving rich shadow details and an introspective, isolated atmosphere, 9:16 aspect ratio, free of watermarks or logos.
