1 point Perspective "Wizard of OZ"

I am taking the perspective class at CGMA..Here is my one point.
For the class you pick a theme, I picked the Wizard of Oz.
This is Dorothy her house and dog , falling  into Munchkin land which was going to have a huge dictator type statue of the witch of the east..but not sure if I will keep that, might be too far out of the normal plot?
 Found out about the New Oz movie in my research☼ I loved the movie as a child, I enjoy the craziness of the books various branches of story as well.
I am working on a garden scene for the Emerald City for the 2 point.
