Environment?

Started off pretty hopeful  but I've sort of trailed off since then.

Less of an actual environment design and more the early stages of what will become the level design, this was meant to be a concept of the Hub world, although I just included one door to get the overall setting and feeling.

Not finished with it but I am loosing focus. 

Was difficult to imagine how the mechanics would work, but doing this has given me a few ideas.
