The background image is not making it's job as telling the user this is an "auto ecole", I don't think is to bold, I like the color and the shades but you need to make the car more clear and find a good place for it, for example down the page after the contact details or up in the header next to the logo (logo on the left and the car in the background on the right) but be careful to have enough white space.

good point, I was already considering it, your comment made it official :)
