Sajama NP - Bolivia (enlarge)

Superb landscape and color contrast is very attractive,I like how that bg cloud looks like the point from where storm will come,amazing to see how this nature looks to 15000ft altitude.

best regards

Beautiful light and color contrast. The white clouds, dark blue sky and that ridge in the sun are stunning. In my opinion, the foreground is a bit drab. I could see two ways: either find something with a bit more interest (though that might distract from the great background) or walk over to that little hill and omit the foreground all together (probably my choice).

Image has potential, cut out the bottom of it, make that sky and clouds bold... possibly B&W and contrasty. Cheers!
