Drawing Paul Newman large scale with a blue pen.

I have recently started a new project that is quite a challenge for me. I stumbled upon an artist who draws large scale portraits of people in blue pen. I pretty much thought it was amazing and wanted to try it myself. little did i know how hard it is to draw things bigger. I posted a picture by the guy and the link to his website below. And the picture of Paul Newman that I plan on drawing.

Yes this is a drawing.What the heck?!?!?!?!
