Boundless Planet 2

Concept art for a video game named Boundless Planet 2.
Humanity's broken off into bands of oil hungry war parties. (are we sure this is scifi?) This low gravity planet used to be the home to mile long cat-like creatures. They've been extinct for hundreds of thousands of years leaving behind one of the most oil rich planets in the galaxy. The world's landscape has formed around their fossilized bones. In these two concepts I wanted to play with vast scale differences, weight and power. In the close-up image I tried to create a ship that's so wasteful it burns oil as fast as it collects it.
