Roughs! I have boxes full of 'em. I think that the point of keeping them is to have the chance to share them. Like this one.
It was a character study for a Fruit drink product. The character had to be spunky, dynamic, good-looking...all those traits that merchandising people think kids relate to the most.
Me? I just let the character come alive. I draw and wonder what would 'he' do in certain situations. If I don't do that then the character lacks life and credibility.
