Post processing was a pain in this one. I am not sure I did the right thing. The highlights on top seemed completely blown but there were some basic details. It did not seem right to have the far background with no detail at all, so I reduced the the highlights in PSE. The result was some information that had some very hard edges with 90 degrees angles (something like large pixels). I blurred them and I obtained the mountain shapes. This edit is probably not the last.
Any feedback on PP as well as composition is welcomed.
