First, the concept is a complete departure from my usual work (where are the animals?!) - I went for a more serious approach, as oppose to my usual humorous takes. This also gave me an excuse to sketch form reference I took at the Metropolitan Museum of Art in New York (so awesome).
I also spent time draining the image of setting, which I usually dig. The result is a much more cerebral illustration. Fun project, might try something like it again some time.
