Thanks for all the great ideas and researching, Heidi!
As we discussed via email, the crane is right on track! haunting, eerie, beautiful.
I'd like to keep those same adjectives in mind for Zoe. She and the crane are very much connected. As much as we can mirror them, especially in the wings, will be helpful.
Baby Zoe is a cute and beautiful human baby, but she is also a prophet with wings.
The Mimi Kirchner images are great. Here are some images I thought could work for Zoe inspiration:


This may be complicating things too much, but I kind of like the idea that she is also part mermaid. As pictured here:

Some specific thoughts:
Crane -
p29 - - it will have to be able to have a detachable/reactachable wing that can stand the wear and tear of falling.
Zoe -
p31 -- Possibly both the actress and the puppet onstage (actress operating puppet), so that we can watch the Baby Zoe to Adult Zoe transition happen more slowly
p45 -- Now actress Zoe is on her own. But, we some dress/style that connects her to Baby Zoe. COSTUMES should be in on this conversation.
Tree -
SET and PUPPET convo--
The actor playing Tree Climber and the physical tree in Act II should be very connected. Perhaps the tree is somehow part of/operated by Tree Climber? Maybe by several actors?
How do the roots grow? How do the branches fall off?
Some inspiration:

Body Parts-
I love that this script is so challenging!! Yay for cannibalism... Mmmmmm.
As stated in Act II, pain is real. There are consequences to actions, and those consequences HURT.
However, the audience will know that the actors aren't really cutting off their body parts. So, what is the most visceral way to convey that they are. We have to think not realistically, but metaphorically. I really encourage all of you to weigh in with ideas/questions/thoughts.
Hope you are all enjoying this last week before your classes begin!
Best,
Lauren
