I had no idea what I was sketching when I started working on this, but I think it's a continuation of the idea of a robot after an apocalypse, trying to deal with sentient animals as he navigates a new reality.
I liked the idea of a Circle K convenience store in the background, but making it a Circle A (with the anarchy symbol), possibly suggesting what caused the collapse of society? Not sure.
I also liked the idea that the only animals that would hang out with the robot were ones of similar color. I'm not sure why yet.
I'll let you know when I figure it out.
