I think a contrasty sky works with this, but the processing is just a little over the top for me. It is a bit distracting, as maria says, and also I don't like losing the ears in the sky.
Yup each to their own regarding PP. I think I got what I was looking for in the end though. I think the sky adds more than it detracts from the overall image - to me it adds drama to the image as a whole which is what I wanted.
