We had similar light and clouds today, good use of the trees there!
#2 would be my fav, you have left enough detail in the water that you get a good sense of water movement - nice!
The water blur thing is so much a matter of taste. The first two both look too blurred to me with the second one being worse because the exposure looks longer. No exif so I don't know how long the exposures were. I normally go for about 1/8th second.
