Nice photos, with very nice (fall-)colors. I would also add some critique here:
#1, #4, obviously, under the tree was shade and you metered on that, so out of the shade it's quite overexposed for me
#2, #5, how the heck does the sky have such a different color than it's reflection on the water. Did you used some ND gradient filter or something like that? Anyway I don't know anything (except PS) that would do something like this. I am not saying that's bad, but it's strange to me.
#3 my absolute favorite!
