Work in progress.

Lots of hatches that will allow views inside.... 

Did I see someone using clear sprue to make a lens? One can but try... 

Huge empty space inside, and no idea what to put in there... 

It would be shame to have the back door shut. 

Reduce the space perhaps, to separate front compartments from the rear. 

Hmm, not too bad for a first attempt for a floor and bulkhead.
