I almost like the clouds better in the origonal plate and something seems a bit weird with the waterfall there seems to be to much mist almost. and im not sure what the blue thing is on the middle left side. And there should be some sort of beach or rock formation near the edge of the water it doesnt seem to natural for the trees to be covered in water with not rock base or sand base for the island to be sitting on.
Im assuming that the blue thing is another waterfall? Get rid of it I say because you don't want to over-do it unless it's absolutely neccessary. Certainly the foreshore is something to work on. Looks promising though.
