Though it was with card board, and far less complex; having attempted a project similar to this I've some idea of how difficult such an undertaking can be.
With that in mind I must give this project full credit in all categories. The scope of this vision brought into reality, and the detail of it's execution, are nothing short of miraculous. Your chose of material honors the topic of the story that you have told through your creation, and adds to the whimsical appeal of this piece.
Thank you for sharing this masterpiece with us. I certainly enjoyed your work.
