I have used the storybook convention dialogue to convey the moral; parents will always love anything you do. This is seen at the point where Mum then says “Your father and I Love your work! We just haven’t seen it yet.” I used this convention because my moral is: “being jealous of people’s success and popularity is alright because as long as you and your parents love what you do not much else matters” and “Setting goals is alright, just don’t let it turn into anger”.
I have also used the storybook convention colour on the front cover
