During the sketch phase, I provided options for a small, youthful "main" character and a "helpful friend" character. The main character "Lando" had to have a distinct shape, possess unlimited curiosity, and have various facial expressions.
The helpful friend (Lisa or Lee) was slightly older than Lando but still a kid at heart. They're more of a leader figure and never hesitate to go on an adventure with Lando.
Final two chosen character designs: Lando + Lisa
