Vexel portraits

Do you feel your vexel portrait is successful and why?
What was the hardest part of completing this project?
If you could Vexel-ize anything else, what would you do?

No, It was hard to get the right shapes and the color to get right. I thought everything was hard to do. If I could vexel-ize any one it would be Steve Jobs, presenting the iPhone or Kevin Durant.
