A giant ice beast rises from snowy ruins, roars and turns everything around into crystal with a freezing shockwave

Prompt

A giant ice beast forming from the environment, jagged crystalline body growing outward, internal light glowing cold blue, frost spreading rapidly across surfaces.
Fully emerges and roars, sending a freezing shockwave that instantly crystallizes everything in its path.
Snow-covered ruins with wind carrying ice particles, ground freezing dynamically as the creature rises.
Starts with macro shot of ice forming on ground, tracking backward as growth accelerates, tilt upward revealing full creature scale, slow-motion roar with visible breath vapor, then wide orbit shot as shockwave spreads, fractal ice patterns forming in real time, cold volumetric lighting and sharp reflections
