later stage in the process of the sketch after composition has been figured out

exploring composition for my scene

My concept depicts a fictional world in which wars are over and war vehichles have been magically turned into wildlife creatures. In these early sketches Im exploring how would the war vehichles wildlife creatures woud look like , how machine-like vs how organic .and natural they will be as well as what will be the nature of the environment around them in the scene Im depicting.
