Hi Slobodan,
Shot #1, I think the composition is spot on, but where the light range is so dynamically extreme between the bright colours of the harshly lit aspens and the muted blue haze of the much darker mountain behind, must have created a lot of CA and colour fringing along those edges, which I then assume you have removed with LR's lens correction tools. Nothing wrong with that, except LR (and PS) when used to tackle some of the more extreme CA problems these types of lighting conditions can create, do so by shifting the edges within the image over each other, a sort of overlapping of one edge with the other to hide the CA problem type of thing, which sometimes can work very well, but at other times can give a false sparkly look to the corrected edge - the tops of the trees seem (to me) to have this effect.
A quick cure I find and what I would normally do as the very last job on an image that has had these problems, is by using PS to duplicate the flattened background layer (Ctrl+J), then using a small soft brush under the blurring tool, gently paint some blur onto the top layer at about 5% along the hard edges until they blend back together more naturally, it doesn't need much to be effective, then either flatten the two layers (Ctrl+E) back into the final image again, or if you find you have gone a bit overboard with the blurring, experiment with the opacity between the two layers until it looks OK and then flatten the image.
Nature very rarely has sharp edges at a distance like this, but LR and PS can introduce that effect into a shot after major CA surgery.
