Looks great, for the most part!! What is RC edition about?
As for the pics, you can do a bit to correct for that back lit situation. Best to shoot with the main light source behind you but sometimes you cannot.
What you do is compose the shot thru the viewfinder, then aim the cameras focus crosshairs at the darker part(in this case, the car itself). Then hold the shutter button down half way to have it focus, meter its light sensor etc. Then keep holding it down half way, but move the crosshairs back to your original composition for the shot you'd like to present. Do this fairly quickly.
Then squeeze the trigger. It will be metered for the darker area on the down-light side of the car. This will allow detail in those areas that are now too dark or just blacked out completely.
You can loose some detail in the extremely light areas, but its a trade off. This is one of the disadvantages of digital cameras. They have a hard time with very bright or very dark areas, even quite pricey ones do, so you have to learn to work around it.
The 5th and 7th ones down are VERY nice, the 7th one could be in a magazine easily if that wee bit of Toyota or whatever it is in the foreground right side(grey car with factory mags) was photoshopped or cropped out.
