i really like the reflection in the loch on the first one, the far hillside looks a little hazy and not quite right, i think a tweek with the levels to either brighten or darken it:shrug:
I would crop the bottom of the shot to remove the near hillside from view as this is distracting.
The sky looks good but maybe needs a bit more contrast for some added punch.
I'm no expert with landscapes or in Post Processing but hope this helps
Thanks
Andy
