Saumin Patel, my collaborator on Mumbai Macguffin and Devi has posted a lot of the behind the scenes type artwork showing the evolution of the concept visually. Do check it out at his blog/portfolio site –  http://pictorialcinema.blogspot.com/

He also has the art of one of my favorite DEVI stories (the KRATHA short from DEVI #11). Scroll down to see it.
