I've just completed a rather large and enjoyable job for The Root Of It, a company that offers support services for children with special education needs, such as autism, or have social, emotional or behavioural difficulties.
The challenge was to create a suitable cartoon character to represent The Root Of It and then use that character to reflect the emotional states, both good and bad, that any child may have in a day-to-day setting. This resulted in just under 50 different cartoon poses and what will hopefully be an excellent resource.
