I think you might beginning to get the hang of this now, Andrew. I like both of them, though I think they would both need sharpening a bit using the unsharp mask.
I think you just need to lighten the front bank a bit, as you've lost all the detail in the grass and it cuts the bottom third of the photograph clean off causing a distraction to your main subject.
I like the long exposure shot of the cars heading up and down the motorway. I think if you'd angled the camera up slightly and used a telephoto lens to zoom in a little closer to the bend in the road it might have just improved it a little, but a good effort nonetheless.
