Command & Conquer 4 - Base Building Doodles

I did some quick napkin concepts back in 2010 to serve as a visual exploration for what GDI and Nod Structures could look like in Command & Conquer 4. C&C4 does not have classical structures or bases, each faction instead having to choose from a single mobile base building, called a "Crawler". I doodled these using different elements from each factions' Crawler, including the Radar Dish, Reactor Modules and structure base, to create different structures out of them.
