You know that feeling you get when you step through airport doors for the first time into a country you've never visited before, or see it through terminal windows for the first time? You have captured that moment here. Only on a different planet and big ass metal fan buildings. I love it.
Quite an exception display of atmosphere and scale in this landscape. Although, I don't really have much experience with Matte paintings, I can still appreciate your design choice as well as over atmosphere implemented into the compositional elements. One thing I could suggest is a bit more clarity in the distance, as some of the elements look a bit unrefined. Nonetheless, good work.
