First off, Welcome to GTP! Enjoy your stay. For your first set of shots, they are pretty nice. They have some unique angles and are composed rather well. The Shelby shot has a really great angle. Your photos definately need some contrast though. You'll notice that there is a certain white "haze" to each shot, as if a layer of tracing paper was layed over the photo. To eliminate this, you need to add contrast. This adjustment increases the difference in value between the colors resulting in a more realistic photo. You may also notice that your photos have some jagged edges on them. More notable would be the oval shaped grill opening on the Cobra. Around the edge there are jagged, pixelated edges. To fix this, you first need a photo editing program (Photoshop, Gimp, etc.). Use a smudge or blur tool on about 7% intensity and run it over the edges, this will smooth out the edges. I realize not everyone is the most well skilled photo editor; I layed out some basics that you should learn over time. Try those tips on your next photos.

These are very good but when you brighten the pictures remeber to increase the contrast as well the main culprit picture that gives it away is the BP Falken RX-7 piccy but good angles.
You are definately improving. The Blitz Skyline shot is a great one. You really got a nice angle showcasing the apex and the overall direction of the drift. Well done!
These are soooooo much better than those other ones. You have increased the contrast meaning you getting better results. My favourite has to be the Plymouth Hemi Cuda ones they just look sweet! Great work. If you have time take a look at my gallery.
