Hello,
In the third picture, I think there is too much saturation - the reeds are just a bit too saturated with colour. The white balance is ok for this type of shot! I would decrease the saturation and increase the vibrance. You could increase the whites and blacks a bit to increase the contrast. There is also some noise in the sky.
A quick correction for an example:

With the other two shots, I would also increase the shadows a bit. In the second photo, the shadows are a bit too dark, and you could add a small amount of overall brightness.
