After Jordan's Photoshop class, he advised me to look more at non-human elements and what would Mars have, creating space on a dusty sandy land a.k.a Las Vegas and Saudi Arabia.
Here are some images I looked at while researching into these two places.
Very different environments but both built on a similar floor. This lead on to looking at desert environments.
I also researched in the images from the Mars Rover.
This gives me a better understanding of colour and texture of Mars.
