flying machines sketch

For this week brief we have to design a room/set/simple environment that is inhabited by our character.
Desert Dash is living in very unpleasant world, full of sandstorms, dangerous creatures and extremely hot weather. He spends most of his time inside his flying machine. It's safer than hiding in a cave, to high for all ground monsters, can store lots of food and supplies. He can also travel really fast between cities.

Thats few quick sketches of the flying machines he might be living in.
