Hamilton Cave

the colors on the sky and water are good, it's a good set up.  i'd desaturate and add contrast to the ground a bit to make it stand out more against the color sky and water.  that way the texture of the rocks will really pop out and you won't get distracted by the color of the ground which could pull attention from the sky.  

You managed this difficult light brilliantly. Congrats. Don't think it could be improved.
