1. Lower f/# so the car pops out a little more.
2. Too Close.
3. Love it.
4. Great idea, just needs to be a little tighter. But otherwise fine.
5. bad reflection.
6. A little tighter, but not anymore that would show less of the car...
7. The sign looks like its the front emblem... I would also use a diffrent angle, at the angle you have it doesnt show what kind of car it is...
8. Like this one. The car just needs to be alittle more towards the center. Its almost being cut off in the frame.
*I feal like an idiot critiqueing pictures... take my critique with a grain of salt.
