It locks the scene first: a dim barn at night filled with loose hay, one lantern casting warm saturated light and deep shadows, a 16mm fairy-tale look with visible grain, soft focus and slight gate weave, a locked-off camera with a slight handheld sway - and the instruction to keep all of it unchanged. The warmth clause matters more than it sounds: without it, models tend to drift toward washed-out, flat lighting.

Then it assigns the cast: the first reference image is the little man in the dark velvet tuxedo who tiptoes forward, stops, raises a finger to his lips and dances with both arms out; the second is the maiden who watches from the hay and reacts. It closes with the wording that keeps identity stable - preserve both faces, hair and outfits from the reference images. One thing it never says: never ask for a face swap or a face replacement. That phrasing gets rejected by content-safety filters on the big video models, and the render simply fails.
