This is one of the two books I have done for my bachelor's degree. It talks about a squirrel who worries so much about everything that it has gotten green. It is a story with morals - it is not worth worrying about things that we have no influence on, and that every situation may became in something good. Minimalist illustrations depict the main scenes without focusing on the background. Designed for the youngest audience - with strong contrast and simple clear shapes. The use of two colors simplifies the printing process and adds a unique character to the publication.
