This picture looks like the focus was on the branch. Before you shoot, make sure you focus is spot on the subject. Make sure to clear any obstructions before shooting. Right now, my eye is sticking to the branch rather than the car. You want people to notice your subject first in a photo.
I always try to avoid objects that look like they are sticking out from the car. Next time, make sure you don't have any trees, people, signs or anything sticking out of the car. Moving your feet would have done wonders.
Never chop of anything from the car. Cropping cars, unless if done right, can be for the worse.
Those are just a few from the bottom that I see wrong. Besides the WB issue, they all could use a little sharping.
And remember, people want to see the car not angles that could break your neck. I always shoot angles, but not to where I get to carried away with them.
