Raul, the lighting really sets the mood here! I think to make this an even stronger image, I'd clone out the lone rock on the right and the plant/flower that is only half in the image at the bottom. Let that heron take the stage by reducing some of the clutter and I think the image would really fly!
Yes, Raul, I'd have recommended the same thing Julie did and it does improve it! The flower was what bothered me the most. I love fog images. Good going!
