Prompt: A photorealistic image depicting a fort located in snowy mountains. The fort is grand and well-fortified, nestled among high, snow-covered peaks. At the gate entrance of the fort, there are two large, imposing black sculptures of panthers, standing as guardians. These sculptures are intricately detailed, conveying a sense of power and vigilance. The overall atmosphere is one of majestic isolation and formidable defense, set in a winter landscape with the fort appearing almost impregnable amidst the harsh, snowy environment.
