Nice work. The house seems a bit too reflective, but otherwise is pretty cool. The atmosphere with the subtle haze is especially nice.
For the moon you could use a simple planet object with an appropriate texture and set it to luminous. It won't provide a lot of actual light unless it's blown out like this, so if you want detail in it you can use fill lights to provide ambient lighting instead. I have a pretty good moon scene going that works this way, based on a texture of the real moon.
