Промпт A golden alien surfer with a sleek, muscular body and a pointed helmet rides a wave on a surfboard. The alien has a humanoid form with intricate details on its skin, wearing black swim trunks and socks. The scene is set against a vibrant ocean backdrop with crashing waves, fluffy clouds, and a half-moon in the sky. In the distance, there are palm trees on a tropical island. The overall style is a retro-futuristic illustration with rich colors and dynamic composition, reminiscent of vintage sci-fi posters.
