Ronza,
Welcome aboard and nice posts to start with!!
Number 1 is at a bit to much of an angle (for my liking) and the focal point appears beyond Ingalls car, the sponsor logo is crisp though.
Number 2 is a good image, nice compression braking and flame shot. I would be tempted to crop it to remove the trees above the sponsor logo though. Don't underestimate the importance of having sponsor logos in your images if you want to have them used later for any possible promo shots. Sponsors love that shit.
Number 3 is a really good panning shot. The car is a bit soft, but the panning has blurred such a busy background, it's a good race shot!
Number 5 is a good shot, subject matter is TOPS!!!! The skin tone is really goos, the image is has a nice DOF with the background nicely OOF. Having the bodies tilted away from the camera helps to make them look slimmer (like they need that).
Number 6 is also a good shot, pity the background is a fence, but you work with what you have. She obviously knows how to pose, lifting her arms away from her sides helps to make her look slimmer, as does the angled pose.
The last two are also nice, despite not being exciting subject matters. Nice lighting on the last one and DOF.
Well done!
