choronor, the car doesn't look abondoned. Just stopped. Perhaps out of gas. I suggest you raise the bonnet, or flatten the right front tire. Or have the car collided with a tree trunk. Give the viewer a visual reason why it's abondoned. Since we can't see the gas guage, you need a more obvious visual reason for the car being abondoned. If you wanted to, you could show foot tracks leading away from the car, or car parts on the ground. Have the car off the road track to suggest that the car came to a stop due to mechnical failure. You might also use vegitation growth on the car to illustrate a long duration of the abondonment.
