"Zentangle" Inspired

Something a little different for a change.  I used to "doodle" at work when someone I was calling had to put me on hold.  One day when I was looking around online, I ran across the term "Zentangle" which was a specific type of "doodle."  I didn't take it literally but used an abstract method of filling up space with multiple patterns.  These take many hours since the details are very small and the paper is 11 x 14.  I would like to try a very large one but that is for another day.  Have a good weekend!
