宇宙飛行士：惑星のリングを滑走する

An 8-second original cinematic science-fantasy 3D animation. One anonymous astronaut in a simple plain white spacesuit with an opaque dark visor glides on two boot-shaped skates along a broad solid translucent golden ring around a small lavender planet. One continuous wide camera tracking shot. The astronaut accelerates from the far left, carves one sweeping turn along the curved ring, scatters sparkling ice particles from the skates, and rushes past camera to the right. Strong lateral travel and dramatic parallax, readable coherent human anatomy, two arms and two legs, consistent ring and planet, beautiful star field. No flags, no mission patches, no insignia, no weapons, no real person or existing film character. No text, brands, logos, cuts, music.
