I'm curious to see where you take it in terms of textures
I like the concept of it (thinking it's some kind of floating cargo truck)
I really like the design you did.
Carefully examine the symmetry of the extensions out of the main cargo pod chassis, on the right-hand side of the vehicle, directly above the small commenting figure. Study them in relation to the establishing line of the lip of the cargo pod.
Perhaps it is my own vision and perception playing tricks on me?
