A Whale's Tale

I don't know what possessed me to take on a Doodle of this magnitude, but the little voice inside me head said Go For It. At 11x14 it's the biggest doodle I have ever done and it took me over 20 hrs to complete. The concept came from an underwater doodle I seen a while back and it sort of grew from that.

 Here it is along with a couple close ups. I hope you like it.
