To answer some of your other questions regarding the details of the work:
The drawing is 48" (four feet) in diameter and thus 150" (12.5 feet) in circumference.
Drawing the piece and editing the still photographs took place over the course of two months with interruption. In all, some 3500 individual photos were taken. . Again, thank you everyone for your most wonderful compliments. I'm very grateful for your considerate recognition.
