Mars Rover Vehicle - design process

Short presentation of Mars Rover concept I made for preparing the book cover for James Crawford's novel MARINER VALLEY. It's based on old original James Crawford's sketch; simple, but very informative. It was great cooperation, I'm happy I could expand his idea. I'm attaching here few rough renders I did during my work on this project.
