Anime Astronaut Portrait

Modern anime key visual, clean thin line art, flat cel shading, vivid colour, dramatic lighting. A portrait of an astronaut in her thirties with her helmet under her arm, Earth reflected in the visor, stars behind. Any person shown is an adult in their late twenties or older, drawn with adult proportions, realistic eye size and a mature face; an original character. No text, no letters, no logos, no watermark.

Prompt tip: Name the light source — rim light, sunset, neon — and the key visual look follows.
