Choque de titanes en lago congelado

**Environment:** A frozen glacial valley under pale arctic twilight. Deep cobalt shadows across the ice field with cold blue ambient light reflecting from massive glacier walls. Snow particles drifting through the air. Frozen lake surfaces acting as natural mirrors for diegetic reflections. **Action:** 15.0s sequence. A towering figure composed of crystalline ice and refracting light engages a magma-armored titan whose body glows through volcanic fissures beneath black stone plating. They clash in rapid close-range combat across the frozen lake. Each strike fractures the ice beneath them, sending radial cracks spreading outward. The magma titan’s punches melt sections of the glacier while the ice giant counters with explosive frost bursts that instantly freeze the molten rock. Velocity Ramp choreography: rapid exchanges freeze into ultra-slow motion when fists collide, showing ice crystals shattering and lava droplets vaporizing before snapping back to full speed as both titans slide across the ice surface. **Camera:** Low tracking shot sliding across the frozen lake surface, reflections capturing both combatants. A sudden upward crane move follows the moment the magma titan is thrown into a glacier wall, ice exploding outward. **Style & Constraints:** 8K resolution, photorealistic volumetric snow, ray-traced reflections on ice surfaces, cinematic cold lighting, 35mm film grain, stable geometry, no flicker.
