Wow, that's one shiney, reflective car! I like the brick reflected on the car, it gives it a cool textured effect. Unfortunatly the reflection of the photographer kind of takes away from it. All in all good job!
A nice idea for a circle, but I don't like the reflection in the paint. You at least should have worn a darker shirt so it wouldn't be quite so noticeable.
Nice pic... I'm a little distracted by the reflection though and think it would have brought out the "round" you were trying to capture if it were not there.
