Although the room on these lines does not inspire me especially, I like how they have used the wallpaper to create a visual impact in a space already somewhat motley. I like how not only has he settled for putting different papers on different walls, but he has gone one step further by following the shape of the wall to put two different patterns.
Another success I see in this room is blue molding that delimits both the roof and the ledge that we see from the front. It is also noteworthy that the papers do not follow the same drawing and even those on the right are a tone that does not even strike, although that is not bad (yes, the animals coming out of the walls are a bit of a house of terror).
Finally, let's look at the contrast with the wall of brick seen which completes a very interesting conjunction with bare frames.
