The first one might have a teensy bit too much processing, IMO. There are some halos and the shadows start to get in to that too-bright-to-be-believable range. The other two are extraordinary though! I LOVE the third one.
thanks everyone for the feedback. Seems #1 is not a crowd favorite. I liked it but looking at it after posting I do think I should have tweaked from the top of the river up to darken and maybe add some contrast. Overall all of these are just basic PP.
I do need to crop or clone out the couple small tree spots on the left of #2
I think #1 is weaker than #3 because it lacks a specific subject. Maybe try cropping some of the left side (cut off the two far left trees, perhaps) and see if that focuses the image better. I know that would center your mountain, but that might be the lesser of two evils.
