Sci-Fi Western Lunar Rider

A cinematic, highly realistic image of a {argument name="subject" default="cowboy"} riding a {argument name="mount" default="white horse"} on the {argument name="setting" default="surface of the moon"}. The figure is seen from behind, wearing a classic hat and a long duster coat, looking out over the barren, grey, and cratered lunar landscape. In the dark, starry space sky above, a large, detailed {argument name="celestial object" default="Earth"} is prominently visible in the upper right. The lighting is dramatic and monochromatic in the foreground, highlighting the textures of the terrain and the rider's coat, contrasting with the blue and white hues of the distant planet to create a surreal yet photorealistic sci-fi western scene.
