As you've asked for critique, I'll give it a go.
The first, whilst I think I can see what you might have been aiming for, there's no a part of this image that's in focus. It's not working for me on any level.
2, 3 and 4 all together....given the time of day and the light available from an already set sun, you've given in to the temptation to lighten the foreground too heavily to bring out detail.
It results in an image (in this case, 3 images), that look like the sky was taken in the evening, and the foreground was taken hours earlier.
The last one, whilst not having the most exciting of compositions, is rather pretty....a typically English summer pastoral scene.
