A stunning battle scene on the ice planet Hoth, featuring AT-AT walkers advancing across a frozen tundra. The image style is photorealistic with epic scale, captured from a low angle, wide shot (f/16, 1/1000s, ISO 400) to emphasize the towering height of the walkers as they loom over the battlefield. The lighting setup is harsh and cold, with the white glare of the sun reflecting off the snow, casting long shadows. Apply motion blur to the laser fire and explosions in the distance to create a dynamic and chaotic atmosphere. Color grading with a cool blue tint enhances the cold, frozen feel, while a subtle HDR effect sharpens the metallic surfaces of the walkers. Add lens flare from the sun to emphasize the intense brightness and snow particles floating through the air for added realism.
