The composition is great with how you framed the clouds and the ground layer. I think you need some shadow recovery on those rocks to add more interest with so little color in the sky. Try out the Luminosity Blending Actions I have put in the Resources, you can help test out if they are any good...
I like this much better! The details in the rocks now add that extra visual interest to help carry the image when the sky can't. I can now sit back and enjoy those ripples in the sand leading into the image.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
