#2 is a nice composition but IMO it is rendered a bit too warm too look natural.
#3 is a nice composition, I would try to "burn" the central part where the tree belt is thinner, it look to me as if there were a lens reflection exactly on that spot, this lowers contrast in the central part of the image (central also in the sense that the eye is immediately driven to that spot). Also beware of the dirt spot in the upper-right corner, in the sky (can be easily eliminated with the "clone" tool).
Cheers

EDIT I see there are two more dirt spots in the sky, again I would "clone them away".
