HDR'ish?
They look beautiful!
The first one really does it for me though, the tone of the blue on the car is just right, subtle but with impact. Just right. Love the brooding sky directly over the car. The point in focus looks to be the center of the car, as the wheel and lights are slightly out of focus... it's just a point of personal taste, but I would have liked the depth of field a bit wider to get all the car in focus.
The second shot has only one problem for me, but again it is pretty subjective: The grass needs to go up a shade to match the shade of the car and sky. If you look just to the left of the front wheel, part of the grass is slightly raised in the tone of its color. That's the tone the rest of the grass should be for me. Still, like I said, it's a subjective point of view on my part.
But great job though, really nice.
