Use first reference image for visual style only: sparse white-space vintage Bible storybook watercolor vignette, loose brown ink outlines, muted earth tones, large clean white/cream paper margins. Use character references only for identity. Keep illustration centered, occupying about 50–60% of canvas, with minimal background and soft watercolor edge fading into white paper. Scene: Song commander lowering his sword at city gate, small Yuan envoy, sparse solemn composition. Negative: no text, no subtitles, no watermark, no logo, no photorealism, no 3D, no anime, no glossy digital art, no cinematic lighting, no dense full-frame background, no crowded battle, no gore, no edge-to-edge scenery.
