I love the way the safehouses look when inside the dome, the way they are all grassy and colorful, like they have been saved from the death of the radius and are allowed to grow and be alive again.
But... From the outside, seeing a giant dome of ash is a little off putting. Like it doesn't belong there. Some suggestions I had was making it so that the shape of the dome is more organic, like the distortion zones, or maybe try changing up the material of the dome and not keep it as that ash/mold texture.
Other than that, I think they are pretty cool
