Thousands of fur-cloaked warriors battle ice giants and beasts in a frozen mountain ravine during a blizzard — dark fantasy

Prompt

Ultra-realistic original dark fantasy battle in a frozen mountain ravine during a blizzard at blue twilight. Thousands of fur-cloaked warriors clash against a horde of towering ice-skinned creatures, tusked giants, and skeletal beasts charging through snow and shattered ice. 
- Massive aerial establishing shot of the canyon, burning siege braziers, avalanching snow, armies colliding across a narrow icy pass. 
- Aggressive tracking shot through the battle line as giant creatures slam into shield formations, axes swing, spears bend, snow and ice shards burst into the air, bodies stagger and fall across the frozen ground. 
- Epic low-angle reveal of an enormous frost giant stepping through the blizzard and crushing the front defense while smaller creatures swarm around its legs, banners tear in the wind, blue fire and drifting snow fill the frame.
