i think the seconds one has a bit of a tight crop on the bottom, and the same thing on the third pic on the left and right side. i don't know what else to say, nice shots.
welcome to photomode...well i think u shud increase the brightness, bringing out the shine helps with detail..overall they look awesome keep it up.. nex just have variety and more angles and ull get more great shots..peace:tup:
You're getting the hang of it...just adjust the brightness and mess with the other settings some more. Also, try not to put the car in the center unless you're trying to give it the muscle look. Otherwise, good job dude.
