Welcome to the forum!
Here is an honest critique - These mountains are very impressive, but as photographs there is more going on that you need to control. In the three photographs that show the sky, the sky is too light and is therefore distracting. If I were reshooting these, I'd wait for better light OR I'd use some type of filter to darken the sky. The darkening of the sky could also be accomplished using photoshop, and would make these shots stronger.
Shot 1 has no sky but it is lacking in contrast. It's a cool shot though.
By far my favourite of these shots is shot 4 - It still needs a bit of work (sky, blue colour cast) but it is a strong photograph.
Hope that helped and hope it wasn't too harsh,
Marko
