What should a Portfolio looks like?

and What is Art Director looking for? 

• A sense of storytelling
• Pictures that set the mood
• Central things that children love
• A full, rich look
• A sense of character
• A sense of anticipation, making the viewer want to know what happens next
• Illustrator’s trust in her or his own skills
• Consistency in character
• Authenticity

I am putting together my art work now and just want to remind myself how it should be.
