Hi, i am having a bit of free time and decided to have a go at some concept work for this challenge, the idea was to get a sense of the layout, general idea of the car and mood of the scene.

Working on the environment geometry and displacements, not shure if the ground as too much detail or the mountains and rocks need finer details...

Environment textured and updated displacements with some instanced rocks. Waybe some desert shrubs for vegetation...

Hi, one more update, now populated with bushes and a small water path, i think i will pause the environment for a while and start on the vehicle.  

After some thinking decided for a different type of vehicle, my initial thoughts... 

Finally got a bit of free time, hope i can get it done in time

Finally some chars for the machines

Runing out of time, on to shading the machine and posing of the chars 

Initial Layout

Got a render, next Fx
