Промпт An astronaut in a detailed white NASA spacesuit riding a powerful chestnut horse at full gallop across a dusty alien desert landscape. The horse is muscular, with flowing mane and tail, wearing a bridle and saddle. Behind them, a dramatic sky filled with swirling clouds, distant stars, glowing planets, and a crescent moon. The sun sets or rises on the horizon, casting golden-orange light and long shadows. Dust kicks up from the horse’s hooves. Cinematic lighting, hyper-detailed, photorealistic, epic sci-fi fantasy, 8K resolution, wide-angle shot, dynamic motion, sense of adventure and wonder.
