Cartoony Modeling

Hi. I want to make a nice not to detailed cartoon style model.
I have tried a few times but it is still proving difficult. Is box modeling or using a lattice best for this sort of work. I know alot of people prefer box modeling for simple catoony characters but a lattice might give a nicer effect. The model ‘Ned the little fish in the ocean’ is about the same simplistic design i want to use for my character. I like the way the head sort of wraps around the eyes.
