Nice composition, though I'd like to see the sky a little less washed out. It looks like a beautiful area, though!

The sloping diagonal lines and verticals of the cliff, combined with the angle of the top work really well together. The sky is the problem, as it is a little bright and draws the eye into the blank space and away from the structure of the cliff. Some people on this site would have just replaced the sky with a stock sky they had in another photograph, which I think amounts to cheating really, but never mind. Post processing such a bland sky is not going to work either, except to make it a dark bland sky perhaps. The real problem, and I get this a lot on my images too, is that the lightness contrast between the two parts of the image is just too great. I am afraid I am at a loss as to how this can be improved, except to resort to HDR.

Nice strong composition. I love the texture in the rock and the shades of green in the foliage.
