There are a lot of things working in this photograph - well captured. Compositionally, I have trouble with the main focus - the arches - being so centrally placed. The natural eye movement is through the arches but my eye doesn't feel compelled to through and around the whole photograph, except for the leaves along the mid-right that are coming out of nowhere. The bottom leaves on the right are fine and are needed for balance, but not the ones halfway up.
I think Slobodan and Tony have already addressed the post-capture processing issues. In addition, consider where you are and when you're there... Given the time & location, there should be a greater feeling of harshness and definitely a colder tone overall. One might argue the colour of the rocks, being so warm, will cause a colour shift, but not in the sky which is clearly not a cold blue, but warmer as if at sunset, yet the shadows do not mirror that time of day.
