Nice memories from your trip. I really like the atmosphere in #3 just I would keep this pic 100% sepia or if all the stones had such a colors it should be a color picture. #1 needs to be straight, lifting lens up works only in close quarters, if at all, but stuff in such a wide, open vistas should be in balance. In #4 I think you should use a spot metering on the figure in the front. #5 is very nice, looks like very good place for b&w photography to. Maybe you should work over such a places little more, looking for best angles of view to extract more drama and romance from it. The last one; I have no idea why you made it b&w. It is very "greyish" and lacks any dynamics. Color might have been much snappier. Also composition there is not very interesting.
