Dwarf Sand Hunter (Character and Environment)

Small project for Concept Artist RPG 7 contest from Smirnov School.
In my story, the dwarf civilization lives in the sunny and arid climate of the east, their fortresses and outposts are scattered across the territory of the Great Desert, their life is slow and stable, and they themselves are traders and scientists.
However, what if the Grail - the heart of the Desert - is stolen by evil elven barbarians? Without the Grail, the ancient sands came in motion, threatening to devour the desert dwarven strongholds.

So, our hero will have to go to the north to return the lost relic and save his people.
