The size and proportions where all done by hand, looking through the image capture application. For the dirt road I used string and needles so I could adjust the road to get the right false perspective, before actually painting the road.
For this shot I had to create some mini props, like the rocks you see in the distance, and the streetlights. The most fun however was trying to make an even thinier car wreck than my other car props.
The material is quite delicate, so cutting out the tiny windows was quite the challenge. If I had the time I would have put some wheels on it, but the car is too far away to notice that anyway.
