Thats noes is pretty much upside down and badly shaped.
A plane that small only needs 2 engines, and the engines need to be bigger.
The main cabin isn't so bad.
This is nothing like a passenger airplane galley. They usually have little counter-space and lots of storage, also, they don't have stoves. Water wouldn't be sitting in the sink, it is directly drained out of the back of a valve in the back of the plane.
