I did some virtual kitbashing in one of the pits, as well. I noticed that one part was an entire famous real-life spacecraft, so I found a low res model of it and scaled it down to fit. Saved me a lot of time, and made me feel part of a great tradition.
Virtually all sci-fi spacecraft models from this era of film-making where made by scratch building a basic body out of various materials, and then gluing miniature model parts to that. Anything from model tanks, trucks, trains, aircraft, and space industry miniatures were used. After a base coat was applied to everything, the models magically transformed into seemingly practical spacecraft.
Bonus points if you can spot the kitbashed part (best viewed in the third render).
I also got some work done on the jawbox (the last render) which so far is all referenced from the full scale set of the Falcon.
