It looks very good on the whole. I too like the gradient of greenery, and the mountain with the snow remains. But somehow I get the feeling the lower half and upper half are not in sync. How shall I phrase this carefully? Lower half seems too big in comparison with the upper half, or vice versa (mountains give an impression of hugeness, also because of the strata, but apparently are quite low/small in relation to the lake shore and up).
I also find the shadows very dark, almost black. That's often the trouble with PT, and I think a cloud layer or fill light should be in order in those cases.
