Jonn13,
Hey and welcome.
Sounds like a great idea there.
The photoshoot would be more different since I have seen a few "car show" dioramas.
One thought is a romantic restaurant (a man and a woman backlit having dinner) and the car parked in the street.
Another thought is the car and someone putting money in the parking meter.
Now there is something everyone can relate to!
Both alow the car to take centre stage but have enough background to make a good "story" and allow you to stop or go as far as you would like with the detailing and so on.
How 'bout a pic or two when it's done?
Cheers, Pete.
