Zendoodle on Duralar

I've been working in the studio again lately.  It feels good!  Yesterday I did a fairly large Zendoodle on Duralar, a translucent material.  I worked with a grid-based doodle and manipulated it so it would appear to be three-dimensional, curving around. 

I drew the inked doodle on one side of the paper, and put color pencil on the other, helping create the illusion of 3-D even more.

Here's the doodle on different color backgrounds.  Which one do you like best?
