I think this is some of the hardest modeling I have ever done. It's not that the forms are particularly hard (although the grape leaves are no picnic), as much as the composition is so complex, and working with plasticine is so slow. Changes can't be made quickly, which means I need to visualize a lot of moving parts that I can't actually see, which always makes me nervous. I have come to be very suspicious of what I think will work vs. what I can see is working. The closest analogy I can draw in my own experience is my limited experience with choreography - trying to compose multiple movements on dancers in space as they overlap in time turned out to be one of the hardest creative exercises I have ever encountered. Particularly because, at the time I refused to use video recording. In those days, I was still more willing to trust what I thought than what I could see.
As I get close to the bottom, I'm having to figure out what that space is like. Does it remain a constant tangle all the way to the bottom, or does the addition of the fisher cat and the chicken require a more rational, dimensional, space? Questions like that keep me up at night.
