When I initially started to design my characters, I first asked myself where these creatures would be situated. As I wanted them to be associated with not only each other, but with their surroundings.

I first came up with a character named Grumpy Gus, a miserable old man living in an old peoples home. But with this initial character I found it hard to think a character for him to interact with.... My initial thoughts were to make a young child character to contrast with Grumpy Gus, but I ditched this entire idea as it was starting to become too similiar to the character design in the Disney Pixar movie, Up!.
Above are some rough, early ideas for Grumpy Gus and an initial idea for his young cohort, before I scrapped the idea.
