A reverse room view: raw Nano Banana against Room angles

An annotated test of MultiAngle output: what to zoom in on and verify.

The same living room seen from the opposite end three ways. The middle image is raw Nano Banana output from one written prompt, not MultiAngle; the right image is the Room angles back-wall view.

What to look at

Neither reverse view is a photograph of that end of the room. The prompted view moves the window to the far wall and adds a door and a picture; the Room angles view keeps the window on its wall but leaves the far wall blank.

Room input made with Nano Banana, not photographed.
