Photoreal Mech Suit in a Crystal Ice Cave

A photorealistic mech suit stands in a vast crystal-blue ice cave. The exoskeleton is weathered titanium-gray with matte armor plates, exposed hydraulics, and frost clinging to joints. A cockpit hatch on the chest glows with teal HUD indicators. Cables and vents have frost; the ground is a polished ice floor reflecting the suit. Surrounding walls are translucent blue ice with hanging icicles, frozen stalagmites, and subtle snow dust. Cold breath wisps from the suit's vents. Soft, cold-blue volumetric light streams through the ice ceiling, creating rim lighting and long shadows. The scene is captured with a dynamic low angle to emphasize scale, with ultra-detailed textures, micro-scratches, condensation on sensors, and subtle wear on the thrusters integrated into calves and back. Cinematic depth of field, 8k realism.
