Olivier Pron was the lede matte painter for Guardians of the Galaxy. His concepts for the movie sets -- and other movies and personal projects -- are extremely cool.
I love the Chris Foss-iness of Xandar, the home planet of the Nova Corps. The rest of his work is equally great. I love the last three paintings in this series.
Olivier Pron works as a concept artist and matte painter at Method Studios. He was the lead matte painter for Guardians of the Galaxy, and a concept artist for Iron Man 3 , Cloud Atlas, Watchmen and X-Men: The Last Stand.
