I just finished a quick concept of chibi tanks. I am looking for a fat cubical siloutette and these going to be modeled accordingly. I tested color palette and some textures over get a feel of these but mainly it will be used as a volume references.
Everyone of these tanks is a cartoon redesign from real tanks of the 2WW. So you have there a Sherman, a Panzer3 … There are a couple of those more to come. Also, you can see the line work version of this here
