Overall, I would say one thing: for each shot, what was your subject?
As I look over the photos, each one has some nice scenery, but none of them have anything that catches my eye. There is no clear subject which my eye wants to rest on, so my eye just wanders around a bit and is left unsatisfied.
I think that you have some very beautiful locations (which could also be very beautiful in color), but you need to find something to shoot in those locations.
Just my 2 cents, value decreasing daily.
