A stunning space cowgirl with luminescent tattoos and a high-tech space helmet, riding a biomechanical horse across a rugged, extraterrestrial desert, blending the essence of a futuristic wild west. Her attire combines traditional cowgirl flair with sleek, metallic accents, and her laser revolvers gleam under the alien sun. The barren landscape, dotted with strange, glowing flora and shimmering rock formations, adds depth to the ultra-realistic, high-definition scene. Stars twinkle faintly in the perpetual twilight, enhancing the enchanting, sci-fi atmosphere.
