确认生成。参数已确定：16:9 横屏，三个连续镜头组成一个完整视频，立即生成，无需再次确认或提问。
The reference images are colored-pencil character design sketches: use them only for design and outfits. Render the video as a photoreal 3D CG game cinematic with dramatic lighting.
Image 1 = PROTAGONIST: [character design].
Image 2 = ANTAGONIST: [opponent design].
Image 3 = ENVIRONMENT: [setting].
FIXED LAYOUT: altar in the background CENTER; protagonist on the LEFT; antagonist on the RIGHT. Nobody disappears, teleports or swaps sides.
LIGHTING: torchlight from the left wall, cool moonlight from the ceiling.
Action: well-choreographed, orbiting camera. No blood, no wounds, no gore.
Sound: heavy impacts, wind, no dialogue.
镜头1: camera pushes in, protagonist draws a weapon, antagonist raises claws.
镜头2: fast exchange, camera orbits.
镜头3: climax, both stay on their sides, protagonist lands ready.
Keep faces and outfits consistent. No text, no numbers, no subtitles, no watermark.
