Thanks a lot for your kind words and thanks also for the tip on how to smooth the objects! When rendering the image I thought that it must be a way to get rid of the sharp edges but I just couldn’t find it. I’ll try it right away.
[EDIT] Actually I originally planned to make this a launch pad for the rocket but finding that the complete structure didn’t look very good in that light setting, I removed it. Also, building a launch pad on another planet isn’t really something that can be currently achieved so no matter how we twist and turn this image, it remains science fiction. The image is cropped in order not to look too empty but there’s definitely room for more buildings and machinery so I think I’ll just keep on working on this one.
