Ituk, a Bronze Age Hunter - Look Development

Imagine a world with not one but two sentient species. Two main landmasses, one equatorial and one temperate, separated for billions of years. The equatorial continent was 'discovered' by Bronze Age explorers who braved the southern polar sea several hundred years ago. Ituk is a descendant of those settlers. He stands on a mountain plateau, holding the reins of a dinosauroid kangaroo-like hopping beast known as Ni. Except she's no beast, she's sentient, and the city where she once lived was utterly destroyed in the final days of the war....

This is a look development painting for a science fiction short film that I'm collaborating on with friends.
