Note the hand holding it up in the pic. No visible base to stay upright. I take it you are not planning to hold it all day and night so some modifications will be required to make this self supporting.
Definitely need to remove quite a few shelves to allow enough light for lower trees and consider placement in the yard. Even well spaced multi storey shelving plays havoc, with lower trees developing long, one sided growth seeking sunlight.
Let us know how it goes when you get this one installed.
