Keep everything in the image exactly the same: the room, the installer, the ginger cat wearing sunglasses, the girl's pose and face. Change only two things. First: remove the sunglasses from the girl's head, show her smooth light blonde hair there instead; the only sunglasses in the image are on the cat. Second: fix the day-night zebra roller blind: all horizontal stripes have exactly the same width and perfectly even spacing, alternating light grey solid stripes and white translucent sheer stripes, every stripe perfectly straight and horizontal, parallel to the window frame; the top roll is hidden in a neat clean white cassette, with no diagonal stripes on it. The blind hangs perfectly straight and level.
