Dark Fantasy Siege Battle with Ogres and Armored Warriors

the prompt

Ultra-realistic original dark fantasy battle. A colossal black fortress stands under storm clouds while thousands of armored warriors clash with a monstrous horde of towering ogres, horned beasts, and feral wolf-like creatures. 

0–4s: wide establishing shot of the battlefield, flaming siege engines, collapsing barricades, arrows filling the sky, banners whipping in violent wind. 
4–9s: fast tracking shot through the front line as soldiers collide with massive creatures, shields buckle, spears snap, armored bodies are thrown aside, mud and sparks fly everywhere. 
9–15s: crane down toward a giant beast smashing through the gate while defenders rush forward in desperate formation, fire, dust, debris, smoke, and chaotic motion filling the frame. Photorealistic, ultra epic, brutal, dynamic, dark, cinematic, massive scale, high contrast, storm-lit atmosphere.
