Love the first image, got some very well behaved trees there and lovely colours
Like the second image, doesn't have the same impact as the first for me
Third image, the sky looks to be blown or nearly blown... Did you use ND grad filters whilst taking the shot or maybe think about adding them after if not. Round pebbly a little too central for my liking, think there could be a stronger composition there if you swung it to the right a little
Forth iamge, again too central for my liking, try moveing to the left or right when taking your image
Fifth image, lovely sky and well exposed forground but too much of it (the foreground) for me... I notice the nice pebbles a little further on, I would have tried using that as my foreground
Last image, I like this alot, would have chopped off the water movement or made more of a feature of it in the forground
Really diverse range of images though, bet you had a fabulous time taking them?!
