I ended up deciding not to use this. The thing that put me off is that there isn't an actual sky since the cell is actually an interior. I went outside after nightfall and the sky is just a dull light gray. No moons, no stars...just gray. That broke immersion for me.

On a bit of an amusing note, every time I look at the Rose Cottage I find myself wondering why I even bother looking at other houses, especially with the pottery area in the basement, the musical instruments upstairs and the other details that make it look like creative, artistic people live there.
