The best science fiction landscapes are the ones that look the most foreign. A great example of this is Brickthing’s MOC “Early Explorations Of Foogara–7.”
“Analysis of preliminary scans indicated that Foogara-7 was a hostile and lifeless planet due to the poisonous Chlorine air and noxious swamps. However, an accidental secondary scan revealed a myriad of flora covering the planet surface, somehow able to survive in the seemingly uninhabitable environment.”
Some of the alien flora is beyond amazing.
