Looks fantastic, I hate to wish insomnia on anyone but it seems to be working for you!
For true large scale insanity, there was a tv show in the UK about model making called 'Supermodels' & in one episode there was a segment about a talented gentleman, (can't recall his name I'm afraid) who specialised in scatch built 1/6 scale WWII models - including the 80cm Schwerer Gustav railway gun. However the true insanity was only revealed once we entered his 'shed' wherein was a 1/2 size Tiger 1E entirely built of wood, while outside were full size, wooden replicas of both an SdKfz 250 & a panzer II Ausf L - such dedication surely wins him all the marbles!
