Cool pictures. I just don’t like the third one, you should have left all the curvature in the rumble strip, you shouldn’t have cropped it, because it disturbed the line flow of the picture.
The other ones a quite good, especially the last one. I love contrast between the green and the yellow.
A tip may be to resize your pictures to a more comfortable size (+/- 900px), as it increases the quality of the picture.
