A single key frame from a modern premium 2D hand-drawn animated film, in the exact drawing style of the character sheets in the images: clean ink lines, flat colour masses, two-tone cel shading, warm painterly backgrounds. Wide 16:9 cinematic composition, characters exactly as on their sheets (same faces, hair, clothes, proportions). No text, no letters, no writing anywhere; any paper is blank or shows only a simple pencil doodle. Use image 1 for the two facing windows and the street. Use image 2 for Otto's exact look. Use image 3 for Lina's exact look. The view across the narrow street at third-floor height, both windows facing each other. In the right window Lina waters her flower boxes with the watering can, humming happily, eyes on the flowers. In the left window Otto peeks out from behind his navy curtain, only half of his face and his round glasses visible, gazing at her dreamily.
