Going back a bit to your question on composition.
By the look of it there was some really stunning scenary around you.
I've got a lot of shots like your first 2 from walking in the alps and up in scotland.
I've come to think that the problem with these shots are that you can't put them into any sort of 'context', there is no horizon, sky or trees to give the picture scale. There is also no real 'focus' or 'subject' to draw the eye.
When you're there its amazing, and when you look at those shots I'm sure you can put them exactly into the right place in your mind, but for someone who wasn't there, they don't 'mean' a great deal.
These are good photos if YOU like them, but they probably won't capture the imagination of anyone else, because they won't make them feel like they are there
Just my thoughts..... Keep it up
