Hi. Great pics.
Some comments though, if I may.
In the first pic, it looks noisy. But I like the colors in the clouds. Pretty difficult to get in my opinion.
In the second pic, would've been better if your flash or some sort of light was used to show the side of the car. And again, it looks noisy.
What camera are you using?
Oh, another tip, try not to place the subject of the photo exactly and entirely in the middle.
