Be brave, Nancy!

The most iconic scene in Stranger Things series was when Nancy and Jonathan confronted the Monster. Nancy with great courage entered into the shadow in the forest where she thought the creater might have been. She found then a portal in the base of a tree. I have no idea how brave Nancy had to be to enter this portal! Anyway after crawling through she found herself in the Upside Down. 

My build is based on the final scene of the fifth episode from first season. Nancy in the forest, standing in front of the tree with opened portal into the Upside Down, where everything is the same, but not the same....
