Good set. Some comments:
#1 - good general view, like the green very much. The sky looks on the verge of being overexposed, perhaps tune it down a bit?
#3 - I would have liked a bit more room in the bottom, which is now too close to the trees and bushes, almost cutting them from the frame.
#4 - excellent movement in the water, with the nice and interesting shrub clinging to the boulder. I would crop a bit from the bottom, to get rid of the intrusive branches.
