At Model Junkyard, the work you do is nice indeed.
I got an idea which would fit right up your line of work-- Ever play, or seen played, the X-Box 360 game "Fallout 3"? Well, it's time frame and story line is, in 2077 there was a nuclear holocaust. The game is set 200 years later, in 2277.
The kicker is-- everything is retro--looks like it came right out of the 1950s, and ALL of it is rusty and beat up. You name it, all the cars, trucks, buses, mailboxes, vending machines, even an aircraft carrier in the Potomac River that has holes rusted through the flight deck which you can see daylight through when your character is on the hangar deck. (By the way, the carrier resembles an Essex class, and all the aircraft look like F-80 shooting stars which were some of our first jet aircraft after WWII)
It would be neat to see a diorama from you with that theme in mind. Yeah I know-
But the convertible's looking good!!
