Brandon, I made that, it's really a shot of my car. I used photoshop to simulate a macro shot with a narrow depth of field like you'd see with a picture of a diecast or miniatures. I also over-saturated it and played with curves (CTRL+M) to give it a more dynamic look by stretching the tones. It works ok on images of car parts, but works awesome on landscapes. Here's the same effects applied to pictures that I took at Hoover Dam and of Hooters in downtown Memphis.
I think it works, at first glance, I think these do look like miniatures.
