Keep the same room, girl, cat, window and day-night zebra blind from the reference image. The step ladder stands right against the wall directly under the window, touching the wall, the installer stands on it face to the window at arm's length from the window frame, his hands on the top cassette of the blind. He is a tall adult man, clearly much bigger than the child. The blind hangs perfectly straight and level, the top cassette is perfectly horizontal and parallel to the top of the window frame. Same dark blue uniform with large white text "ТОЧКА-ЖАЛЮЗИ" on the back. 3D animated cartoon style, soft cinematic lighting, highly detailed, vertical 9:16
