Cover For New Book Project - The Pieces of Our Puzzle

I'm in the process of writing the 2nd edition of a book titled The Pieces of Our Puzzle that I originally published in 1993. It provides a holistic synthesis of the world's major schools of psychology. It's a book that can help people find the pieces of their puzzle, so to speak, to stay centered, strong and at peace within themselves during any time, but especially during turbulent times. I need an artist to create a nice and attractive design that incorporates the concept of a puzzle into the design. It's a standard 6X9" book. I'd like it to be colorful. Maybe a picture of a person's head that looks like a puzzle? I am open to new ideas as well.
