I'm loving that colony illustration, i feel this background pictures are really important and the guys are doing a great job with the details and environment feeling.

I can't suggest any changes because i love it, but i can say that the themes maybe can change, i would like to see the same or another picture but red with the house destroyed with a volcano making some damage or something like that, maybe you can re-use the foundation and make another ambient just with some little changes.

Thats it!! love the work keep going.
