At the risk of sounding a little harsh, these are nice snapshots. I do not get the feeling of a rainy afternoon - yes it is overcast, but how would I know it is raining? For the specific images:
#1. the foreground is very cluttered and the horizon line is too close to the centre of the image, so it is hard to tell which part of the image is more important, the foreground or the sky. There is that bit of a tree poking into the image on the right and this is a distraction that I would have cropped out.
#2. the foreground is very cluttered. There is a tower of some sort in the middle part of the image. I would have cloned it out. There are patches of a "brownish" vegetation on the right and left side of the foreground and I found these distracting.
